Hi,
It is a series of odd prime numbers. Prime numbers is a that numbers which is only divisible by itself and 1.
so next odd number in the number series which is divisible by only itself and 1 is 17. So the next number given series will be 17.
Hope it helps.

Hey, if it is a series of prime numbers, then 5 must have been included..! And in case you take it as series of alternative primes, then there is no prime between (7 and 11) and also between (11 and 13).

🤔 in that case you can also take it as a possiblity of +4,+4,+2 repition series than in that case the cycle will restart with +4 +4,+2 this logic also give 17 as the answer. Look at follow-
3+4= 7
7+4 = 11
11+2= 13
13+4 =17
17+4 = 21
21+2= 23 ....and so on.
3+4= 7
7+4 = 11
11+2= 13
13+4 =17
17+4 = 21
21+2= 23 ....and so on.
