What is the next number in the series: 1, 4, 9, 16, 25, ?
Correct answer: C. 36
- A. 30
- B. 32
- C. 36
- D. 40
Explanation
The series is made up of consecutive perfect squares: 12 = 1, 22 = 4, 32 = 9, 42 = 16, 52 = 25. The next number in the series is 62 = 36. Therefore, the correct answer is 36.Options 30, 32, and 40 are not perfect squares and do not follow the pattern established by the series.

About Logical Problems
Logical problems present several conditions about people, objects, events or choices and require their possible arrangements to be tested. They cover constraint-based reasoning, rankings, matching, grouping, scheduling and elimination, with attention to the difference between a complete solution and a possibility that merely satisfies one condition.
