Check your answer:-

**Next number**

**Next to next number**

Answer With Explanation

there are two series in this puzzle,

First is 11,19,26,32,37 & second is 15,18,21,24

First is 11,19,26,32,37 & second is 15,18,21,24

first series is AP with a decreasing difference

11 -> 19 => 8

19 -> 26 => 7

26 -> 32 => 6

32 -> 37 => 5

thus next number should be 37 + 4 => 41

second series is AP with a difference of 3

15, 18, 21, 24 => next number should be 27
