Find first three non zero terms in series expansion where the argument of funstion is small

ln(5+p)

2. Relevant equations

3. The attempt at a solution

The only way I could think how to do this is by saying ln(5+p) = ln(1+(4+p)) and expanding to

(4+p)- 1/2(4+p)^2 + 1/3(4+p)^3 - .... however, I imagine that this would only work if p was approx -4.
