1/4(5^k - 1) + 5^k = 1/4(5^(k+1) - 1)
If you're having a hard time with the exponents and all that, I typed it in Word and uploaded a picture of it

So at any rate, can anyone figure this out? My dad and I tried for like half an hour and finally gave up! We got it a few steps down and plugged in some sample numbers and proved that it worked, but we just couldn't get it to where one side was exactly the same equation as the other.
Anyone wanna' give it a shot?
