plz help ​

Answer 1

n = 1

2n = 2•1 = 2

2n + 1 = 2•1 + 1 = 2+1 = 3

n = 2

2n = 2•2 = 4

2n + 1 = 2•2 + 1 = 4+1 = 5

n = 3

2n = 2•3 = 6

2n + 1 = 2•3 + 1 = 6+1 = 7

n = 5

2n = 2•5 = 10

2n + 1 = 2•5 + 1 = 10+1 = 11

2n = 18 |:2

n = 9

2n + 1 = 18+1 = 19

2n + 1 = 25

2n = 25-1

2n = 24 |:2

n = 12
