Study the series given below and locate the number that is missing:
5, 10, 17, 26, ______
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 37
Look at the pattern in the series:
5, 10, 17, 26, ___
Differences:
- 10 − 5 = 5
- 17 − 10 = 7
- 26 − 17 = 9
The differences increase by 2 each time.
Next difference = 11
So,
26 + 11 = 37
