Question:
What is the equation for the nth term?
{eq}-2, 1, 6, 13, 22, 33, 46. {/eq}
Nth Term
Nth term is a very important tool to find out the next term in sequence or even further down the sequence.
For example, if the equation is {eq}a_n = n^2 + 1 {/eq} and you are asked to find the 100th term. All you need t do is substitute 100 into the {eq}n {/eq} to get {eq}(100)^2 + 1 = 10,001 {/eq}.
