Question

3 4 6 9 13 what is the next number in the series

Answer 1

3+1=4

4+2=6

6+3=9

9+4=13

13+5=18...

Answer 2

Here it is

3, 4, 6, 9, 13.

Checking the difference between each numbers it is

4 - 3 = 1

6 - 4 = 2

9 - 6 = 3

13 - 9 = 4

So their differences are coming in numerical order i.e, 1is getting added in each differences.

There the next number that will be

13+(4+1) = 13 + 5 = 18.

18+(5+1) = 18 + 6 = 24

Therefore, the next numbers in the series will be

3, 4, 6, 9, 13, 18, 24.
