Determine whether the formula is explicit or recursive. Then find the first five terms of the sequence.

 

a^n= 2a^n-1+3,   Where a^1=-2

 

I know it's Recursive

 

Now all I need is the first five terms of the sequence.

It is recursive:
First term= - 2
2nd term =2 * (-2) + 3 = - 1
3rd term =2 * (-1) + 3 = + 1
4th term = 2 * (+1) + 3 = + 5
5th term = 2 * (+5) + 3 = + 13
