Curso completo de Raciocínio Lógico para Concursos Públicos 2013 Aula 13

Summary

The video script discusses a series of logical sequence exercises from the Carlos Chagas Foundation, aimed at sharpening analytical skills. It covers various patterns, including geometric shapes, clock-like figures, and weekly swimming routines, to identify cycles and predict outcomes. The presenter also solves a trick question about the return date of travelers, emphasizing the importance of careful reading and logical reasoning to arrive at the correct answer.

Takeaways

• 😀 The video is a lesson focused on logical sequences and pattern recognition in a series of exercises, primarily from the Fundação Carlos Chagas (FCC).
• 🔍 The first exercise involves recognizing a pattern in a sequence of shapes and predicting the 100th figure in the sequence, which is a painted hexagon based on the established cycle.
• 📚 The second exercise is about identifying the position of a figure in a sequence that is cyclical, similar to a clock, with the 13th figure being the same as the first.
• 🤔 The third exercise asks to find a missing figure in a sequence of figures drawn in lines, following the same construction pattern, with the missing figure having a rectangular head and a downward arm.
• 🏊 The fourth exercise is about calculating the day of the week on which José will swim for the 100th time, given a pattern of swimming every four days starting on a Saturday, which turns out to be a Wednesday.
• 🗓️ The fifth exercise involves a tricky word problem about the days before and after 'tomorrow', with Regina and Roberto returning three days before the day after 'the day before tomorrow', which is a Sunday.
• 🔢 The video emphasizes the importance of understanding cycles and patterns in sequences to solve the exercises, which is a common theme in FCC's exams.
• 📉 The presenter uses a step-by-step approach to solve each problem, breaking down the complexity into manageable parts and explaining the logic behind each step.
• 📈 The video aims to help viewers practice and improve their skills in pattern recognition and logical reasoning, which are crucial for exams like those from the FCC.
• 👨‍🏫 The instructor provides two different methods to solve the second exercise, showcasing versatility in problem-solving approaches.
• 📝 The script is a transcript of an educational video, likely aimed at students preparing for entrance exams or similar assessments.

Q & A

What is the main topic of the video script?

The main topic of the video script is about solving logical sequence puzzles, specifically focusing on patterns in shapes and figures, as part of a class or lecture.

What is the first type of sequence discussed in the script?

The first type of sequence discussed is a pattern of figures that includes a square, ball, triangle, cross, and hexagon, which repeats every five figures.

How is the color pattern of the figures determined in the sequence?

The color pattern of the figures is determined by a cycle of four, with the figures being white, striped, and painted in a repeating order, and multiples of four being painted.

What is the 100th figure in the sequence according to the script?

The 100th figure in the sequence is a painted hexagon, as it is a multiple of 100, which is a multiple of 4, and thus follows the pattern of being painted.

What is the second type of sequence that involves figures resembling a clock?

The second type of sequence involves figures that resemble a clock with pointers, where the position of the pointers changes in a cyclical pattern, similar to the hours on a clock.

How is the position of the next figure in the clock-like sequence determined?

The position of the next figure in the clock-like sequence is determined by the pattern where the 'pointer' moves as if it were the hour hand on a clock, advancing one hour for each figure.

What is the answer to the question about the position of the figure that will be the same as the first one?

The 13th figure will be the same as the first one, as the sequence is cyclical with a cycle of 12 figures, and the 13th figure completes the cycle and starts it anew.

What is the third type of sequence discussed in the script?

The third type of sequence involves figures drawn with a construction pattern that includes elements like a triangle head, ball head, and square head, along with different arm and leg positions.

How is the missing figure in the construction pattern determined?

The missing figure in the construction pattern is determined by identifying the pattern of elements in the lines above and below the missing figure, and then choosing the figure that completes the pattern.

What is the fourth question in the script about José's swimming routine?

The fourth question is about determining the day of the week when José will go swimming for the 100th time, given that he swims every four days starting on a Saturday.

How can you determine the day of the week for José's 100th swimming session?

You can determine the day of the week for José's 100th swimming session by dividing 100 by the cycle of 7 days in a week, which gives you 14 complete cycles with 2 days remaining, indicating that the 100th session will be on a Wednesday.

What is the fifth question in the script about Regina and Roberto's travel?

The fifth question is about determining the day Regina and Roberto returned from their trip, given that they returned three days before the day after the day before tomorrow, and today is Tuesday.

How can you find out the day Regina and Roberto returned?

You can find out the day Regina and Roberto returned by first identifying that 'the day before tomorrow' is Wednesday, making 'three days before Wednesday' as Sunday.
