A Partial Sum is a sum of sart of a sequence, where a sequence is a set of things (usually numbers) that are in order.
Partial Sums are often written using Σ (called Sigma) to mean "add them all up":
When you should calculate the kth partial sum of an arithmetic sequence, you need to add the first k terms. If k is large, than you will need a long time to calculate the sum. Fortunately, you can use a general formula instead of plugging in each of the values for n.
The first thing you should do is to find the first term of the sequence.
Then you should find the kth term of the sequence.
Then you should use the formula for the kth partial sum of an arithmetic sequence to find the sum.
