In order to prove this by induction, we first need to prove the base case, i.e. prove that P(1) is true:

So, the base case is ok. Now, we need to assume
and prove
.
states that

, we can substitute the sum of the first n terms with their expression:

Which terminates the proof, since we showed that

as required
The number is -11/4 less than -8/3
