The first four terms of the series probably refer to the first four partial sums.
which you can compute either by adding one term at a time, or using the well-known formula,
(I can provide a link to a derivation I gave in a nearly identical question in the comments)
The series converges as
if and only if 
, which is certainly the case here, since 
.
Extrapolating from the formula above, the sum of the convergent series is
so the sum for this series is
.
