# Math Patterns

### Choose the correct option in place of question mark (?) in the following series:

2, 7, 9, 3, 8, 11, 4, 9, 13, (?), 10, 15.

(a) 3

(b) 4

(c) 5

(d) 6

Solution:

In the series when we add the first two numbers we get the third number.

2 + 7 = 9

3 + 8 = 11

4 + 9 = 13

(?) + 10 = 15; now, 15 – 10 = 5; since 5 + 10 = 15
