Multiple choice general knowledge math & puzzles

In each series, look for the degree and direction of change between the numbers. In other words, do the numbers increase or decrease, and by how much Look at this series: 58, 52, 46, 40, 34, ... What number should come next?

  1. 14

  2. 15

  3. 21

  4. 23
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This series follows a clear pattern: each number decreases by 6 (58→52→46→40→34). To continue the pattern, subtract 6 from 34 to get 28. This is a simple arithmetic progression with a constant difference of -6.

AI explanation

To find the next number in the series 58, 52, 46, 40, 34, ..., we need to determine the pattern or rule that governs the sequence.

By observing the given series, we can see that each number is decreasing by 6. Therefore, to find the next number, we need to subtract 6 from the previous number.

58 - 6 = 52 52 - 6 = 46 46 - 6 = 40 40 - 6 = 34

So, the next number should be:

34 - 6 = 28

However, none of the given options match 28. Therefore, we need to reconsider the pattern.

Alternatively, we can observe that each number is decreasing by 6, and the difference between the numbers is decreasing by 1. In other words, the decreasing pattern is changing.

58 - 6 = 52 52 - 6 = 46 46 - 6 = 40 40 - 6 = 34 34 - 6 = 28

From the pattern, we can determine that the next difference should be 5. So, we subtract 5 from the previous number:

28 - 5 = 23

Therefore, the next number in the series should be 23.

Hence, the correct answer is option D) 23.
