Question

Number Series: What comes next in the series?
2, 6, 12, 20, 30, ?

• A. 40
• B. 42
• C. 36
• D. 38

Hint:

Check the difference between terms to identify the pattern in number series.

Answer 1

The Correct Option is B

Observe the differences between consecutive terms:

6 - 2 = 4
12 - 6 = 6
20 - 12 = 8
30 - 20 = 10

Differences are: 4, 6, 8, 10 — increasing by 2 each time.
The next difference should be: 10 + 2 = 12

So, next term = last term + next difference = 30 + 12 = 42

Answer: 42
