    So just slide a cheeky 2^k into the bracket being multiplied by 6 giving you: f(k+1)=2\cdot 2^{k}+6(6^k+2^k)-6\cdot 2^k

    From your last step, go to 2(2^k)=6(2^k)-4(2^k)

    What would be the point in doing that though? If you're only going to subtract it afterwards?

    Because then you obtain f(k) in the expression.

    It's an equivalent statement, so just make the statement because you can so you can show what the question asks. Like C1 Indices
