The next number in the series 2, 5, 11, 20, 32, 47 is

Solution:

The series of numbers given are

2, 5, 11, 20, 32, 47

We know that

2 + 3 = 5

5 + 6 = 11

11 + 9 = 20

20 + 12 = 32

32 + 15 = 47

Here the multiples of 3 are added to the numbers to get the next number

So we get

47 + 18 = 65

Therefore, the next number in the series is 65.

The next number in the series 2, 5, 11, 20, 32, 47 is

Summary:

The next number in the series 2, 5, 11, 20, 32, 47 is 65.
