Question : 40 of 51

Marks: +1, -0

1,5,13,25, 41, ?

Solution:

Concept:

The series follows a pattern where the difference between consecutive terms increases by a constant amount.

Explanation:

Step 1: Compute the differences between consecutive terms.

5 - 1 = 4

13 - 5 = 8

25 - 13 = 12

41 - 25 = 16

The differences are

4, 8, 12, 16

, which increase by

4

each time.

Step 2: The next difference should be

16 + 4 = 20

Step 3: Add this difference to the last term:

41 + 20 = 61

Answer:

61
