Question

I need the answer to the next number in the number series, 4, 8, 3, 6, 12, 7, 10.

Answer 1

Looking at the series, the operations are multiply by 2, subtract 5, add 3 repeated in that order. The next item is 10*2 = 20.

Answer 2

I like double, then subtract 5, then add 3..... so the nexd terms in your sequence are 20, 15, 18, 36,31, 34.....
