Algebra C and C Arithmetic Sequence

What is an Arithmetic Sequence?

• expresses the nth term of a sequence in terms of n

• A sequence where each term increases by adding/subtracting some constant k. This is in contrast to a geometric sequence where each term increases by dividing/multiplying some constant k.

• defines the terms in a sequence by relating each term to the ones before it

• A sequence where each term increases by multiplication or division.
