The pattern is +5, -7... the answer is 6
11, I think, though I'm not positive.
-11 Pattern: Subtract 1, subtract 2, subtract 3 and so on.
The pattern goes -1 x5 so the next number is 19x5 which is 95
11205 Pattern rule: Start at 1. Multiply by 7, and subtract 2.
1/2 then 1/4 1/8 1/16 1/32
You are multiplying by 5 and taking 1 away, so the next value is 36719.
