Finally get to swoop in and answer!
Each new value is 1 plus twice the previous value.
First value is 1. Then,
1 plus twice 1 = 3, the second value.
Second value is 3
1 plus twice 3 = 7, so
Third value is 7
and so on (this is merely a check)
Answer:
It's choice 2.
Explanation:
The nth value is 1 more than twice the previous value
- for example, 15 = 2*7 + 1.
