It could be 2 because the rest are odd number
It could be 9 because the rest are prime numbers
13 because it is a 2-digit number? or because the third # in the set of odds (1,3,5,7,9...) would be 11, not 13... ~Im a secret
-11
It is 11 which is also a prime number

11/13
It probably is 18 because if divided by 2 they are 3, 5, 7, 9, 11 and 13 but 9 is not a prime number
-11
48 does not belong. The pattern is (times 2) then (plus 3). The last number should be 58.
Actually the next number in the sequence is 17 A 19 , 23 , 29 , 31 ,.......... Prim number
It is 11 which is also a prime number
48
2 and 11.

13
Since both 11 and 13 are prime numbers, the LCM of these 2 number is 11 * 13 = 143. All multiples of 143 are multiples of 11 and 13 as well
