# Summation of series – Further Maths Paper 1

Candidates should be able to:

• use the standard results for $$\sum r$$, $$\sum r^2$$, $$\sum r^3$$ to find related sums;
• use the method of differences to obtain the sum of a finite series, e.g. by expressing the general term in partial fractions;
• recognise, by direct consideration of a sum to n terms, when a series is convergent, and find the sum to infinity in such cases.
