Question

What will come in place of question mark (?) in the following number series?

8, 12, 18, 26, 36, ?

1. 38
2. 42
3. 48
4. 72
5. 46

Answer 1

Correct Answer - Option 3 : 48

Considering the above series,

8, 12, 18, 26, 36, ?

The logic of the series can be explained as,

12 - 8 = 4

18 - 12 = 6

 26 - 18 = 8

36 - 26 = 10

By observing the pattern, we can write

? - 36 = 12

⇒ ? = 48

∴ The value of ? is 48
