**Find the next term of an arithmetic sequence, given the first few terms**are broken up into 2 exercises on Khan Academy that appear in the Precalculus Math Mission and Mathematics III Math Mission:

*Arithmetic Sequences 1*and

*Arithmetic Sequences 2*. The first one is basic and the second one is a bit more challenging and harder.

## Arithmetic Sequences 1

Arithmetic Sequences 1 requires students to find the next number in the arithmetic sequence given in the exercise for completion. 3-5 terms of the arithmetic sequence are given. Exercise Location: Arithmetic Sequences 1 Exercise

## Arithmetic Sequences 2

Arithmetic Sequences 2 requires userz to find a certain term in the arithmetic sequence given that a formula to find each term in the sequence. The formula is set up as so: This one is the hard one.

$ {a_i} $ = first term + increment between terms times $ {(i-1)} $

This formula is explained here: Equations of sequence patterns
