WILL GIVE A BRAINLIEST PLEASE HELP!!

Write the first 4 terms of the sequence if a(4)=36 and a(n)=1/2a(n-1)+12.

A.
36, 30, 27, 25.5
B.
120, 72, 48, 36
C.
456, 216, 96, 36
D.
36, 48, 72, 120

Respuesta :

a(4) = 1/2 a(n - 1) + 12 = 36
1/2 * 3a  + 12 = 36
3/2 a = 24
a = 16
 
so first term = 1/2 * 16 (1 - 1) + 12 = 12
which  is different from any of the choices.

you sure you have the question right? Or maybe i misread it.
