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

Analyze the differences between successive terms:

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

The sequence of differences is 4, 6, 8, 10, exhibiting a consistent increment of 2.
The subsequent difference is calculated as: 10 + 2 = 12

Therefore, the next term is determined by adding the next difference to the last term: 30 + 12 = 42

Answer: 42
