Front

What is the definition of an Arithmetic Sequence?

Back

A sequence of numbers in which the difference between consecutive terms is constant.

Front

What is the definition of a Geometric Sequence?

Back

A sequence of numbers in which each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.

Front

How do you find the common difference in an Arithmetic Sequence?

Back

Subtract the first term from the second term.

Front

How do you find the common ratio in a Geometric Sequence?

Back

Divide the second term by the first term.

Front

What is the formula for the nth term of an Arithmetic Sequence?

Back

a_n = a_1 + (n-1)d, where a_1 is the first term and d is the common difference.
