This is a take home test so I don't want the answer because I want to know how to do it.

this is what I have done so far.

1. prove P(1) is true:

5^(1) -1 = 4 which is divisible by four so this checks

2. prove P(k) is true:

5^(k) - 1 is divisible by 4

5^(k) - 1 = 4(m) where m is some number

3. P(k+1):

5^(k+1) - 1 =4( ____ )

from here I have no idea what to do..if someone could help me with a hint or something that would be great....
