What will come in place of question mark (?) inthe following number series'
23 32 45 62 83 ?

Options

A. 116
B. 106
C. 102
D. None of the above

Answer

To find the missing number in the series 23, 32, 45, 62, 83, ?, we can analyze the differences between consecutive terms.

1. **Calculate the differences between consecutive terms:**
- 32 - 23 = 9
- 45 - 32 = 13
- 62 - 45 = 17
- 83 - 62 = 21

So, the differences are: 9, 13, 17, 21.

2. **Identify the pattern in the differences:**
- The differences themselves are increasing:
- 13 - 9 = 4
- 17 - 13 = 4
- 21 - 17 = 4

This shows that we are adding 4 to the previous difference.

3. **Find the next difference:**
- The next difference after 21 would be:
- 21 + 4 = 25

4. **Calculate the next term in the series:**
- To find the next term after 83, we add the next difference (25) to the last term (83):
- 83 + 25 = 108

Thus, the missing number in the series is **108**.
