Answer:

C

Step-by-step explanation:

The problem is where does n start?

a1 = 1/2

a2 = 2*(a1) + 1/2

a2 = 2*(1/2) + 1/2

a2 = 1 + 1/2

a2 = 1 1/2

=========

a3 = 2*a2 + 1/2

a3 = 2*(1 1/2) + 1/2

a3 = 3 + 1/2

a3 = 3 1/2

==============

a4 = 2(3 1/2) + 1/2

a4 = 7 + 1/2

a4 = 7 1/2

==============

an = 2*a_(n-1) + 1/2

The answer is C
