Question

rearrange or change both sides of the equation with algebra to show both sides are equal:

Answer 1

\[k2^{k+2}+2+(k+1)2^{k+1}=(k+1)2^{k+3}+2\]

Answer 2

@strobe: (this is for the proof)

Answer 3

I've lost the other thread, did you try my suggestion?

Answer 5

Im not sure if i know how to do the way you suggested, i've only learned to do it one way

Answer 6

Okay, from the looks of it, your above equation is false, so you've probably slipped up somewhere.
Essentially, I would calculate the RHS for k + 1 and then leave it alone.
Then try and change the LHS to the same form as the RHS but substituting in the the RHS of p(k) into the LHS.
