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.
= first term + increment between terms times
This formula is explained here: Equations of sequence patterns
