What is the next number? 81, 27, 9, 3, ?
Correct answer: C. 1
- A. 0
- B. 2
- C. 1
- D. -1
Explanation
The sequence follows a pattern where each number is the result of dividing the previous number by 3. Starting with 81, dividing by 3 gives 27; dividing 27 by 3 gives 9; dividing 9 by 3 gives 3; and finally, dividing 3 by 3 results in 1. Therefore, the next number in the sequence is 1. Other options such as 0, 2, and -1 do not follow this divisional pattern.

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.
