Verified Answer
Direction: In the following question, various terms of a number serie...
There are two series merged together.
One is: 10, 17, ?, 31
Here to get a new number add 7 to the previous number.
10 + 7 = 17
17 + 7 = 24
24 + 7 = 31
Other one is: 3, 8, 18
Here to get the next number to multiply the previous number by 2 and add 2.
3 × 2 + 2 = 8
8 × 2 + 2 = 18
So, the missing term is 24.
Hence, the correct option is (A).

Missing Term Calculation:

To find the missing term in the given number series, we need to analyze the pattern followed by the numbers provided.

Pattern Analysis:
- The series starts with 10 and then decreases by 7 to reach 3.
- The next term then increases by 14 to reach 17.
- The following term decreases by 9 to reach 8.

Calculation:
- Starting from the last known term 8, we need to increase by 12 to get the next term in the series.
- Therefore, 8 + 12 = 20

Hence, the missing term in the series is 20, which corresponds to option A.
