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.

Find the next term of an arithmetic sequence, given the first few terms

Exercise Example

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.

= first term + increment between terms times

This formula is explained here: Equations of sequence patterns
