What will come in place of the question mark (?) in the following number series? 2, 6, 12, 20, 30, 42, ?
Answer: Option C
Solution (By JKSSB Mock Tests)
The differences between consecutive terms are: 4, 6, 8, 10, 12. These are consecutive even numbers. The next difference should be 14. Therefore, the next term is 42+14=56.[reference:6]
