- Let's look at the given series: 3, 5, 10, 18, 29, ?, 60.

- Observe the differences between consecutive numbers:

- 5 - 3 = 2

- 10 - 5 = 5

- 18 - 10 = 8

- 29 - 18 = 11

- The differences themselves form a series: 2, 5, 8, 11.

- Notice that each difference increases by 3 (2 + 3 = 5, 5 + 3 = 8, 8 + 3 = 11).

- Continuing this pattern, the next difference is 11 + 3 = 14.

- Add this difference to the last known number in the original series: 29 + 14 = 43.

- So, the missing number is 43.

- Correct Answer: Option 4: 43
