Question

what is the next number in the series?
5, 15,10,13,15,11

Answer 1

Answer:

this is right answer is 14

Answer 2

Step-by-step explanation:

5 , 15 , 10, 13 , 15 , 11, 20 , 9 , 25

5 + 5 = 10

15 - 2 = 13

10 + 5 = 15

13 - 2 = 11

15 + 5 = 20

11 - 2 = 9

20 + 5 = 25

We're skipping one number each. The first is added by 5 and the next number is subtracted by 2.

Hope it helps.
