8 does not belong
Sequence is to add 1 for the first number, and double the next result, and then add 1 to that result, and double again...
Correct Sequence
2 (+1) 3 (x2) 6 (+1) 7 (x2) 14 (+1) 15 (x2) 30
2-3-6-7-8-14-15-30
(2+1) = (3 x 2) = (6 + 1) = (7 x 2) = (14 + 1) = (15 x 2) = 30 ....
So 8 does not belong in the above series.
