f(1) = 0
f(2) = 2* f(1)+4*f(0)=2+4k
f(3) = 2*f(2)+4*f(1)
= 2(2+4k)+4
= 4+8k+4
= 8+8k
f(4) =2*f(3)+4*f(2)
=2(8+8k)+4(2+4k)
=16+16k+8+16k
= 32k + 24
f(4)=88 means
32k+24=88
32k =64
k= 2

The answer is correct but not the solution.

{{
f(0) = k
f(1) = 1
f(2) = 2 * 1 + 4*f(0) = 2 + 4k
f(3) = 2 * f(2) + 4*f(1) = 2*(2+4k) + 4 = 8k + 4 + 4 =8k + 8
f(4) = 2*f(3) + 4f(2) = 2*(8k + 8) + 4*(2 + 4k) = 16k + 16 + 8 + 16k = 32k + 24 = 88
}}

f(4) = 2*f(3) + 4*f(2)
f(4) = 2*(2*f(2)+4) + 4*f(2)
f(4) = 8*f(2) + 8
f(4) = 8*(2 + 4*f(0)) + 8  
32K + 24 = 88
k = 2
