The next number in the sequence is 15 - the sequence goes x2, +2, -1

75 (times 3, divided by2, plus 1)

x 2 + 2 - 1 is the repeating sequence 1 x 2 = 2 2 + 2 = 4 4 - 1 = 3 3 x 2 = 6 6 + 2 = 8 8 - 1 = 7 7 x 2 = 14 14 + 2 = 16 16 - 1 = 15 the next number is 15

The sequence doubles for the first one, then adds two for the next number, then subtracts one for the third, then repeats. So the next number is 15.15.It's a three step operation : x 2, + 2, -1,The step after 16 is -1 which gives 15.
