Front

Define an arithmetic sequence.

Back

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is constant.

Front

What is the common difference in the arithmetic sequence 2, 5, 8, 11, ...?

Back

Front

How do you find the nth term of an arithmetic sequence?

Back

Use the formula t(n) = a + (n-1)d, where a is the first term and d is the common difference.

Front

What is a geometric sequence?

Back

A geometric sequence is a sequence where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.

Front

What is the common ratio in the geometric sequence 2, 6, 18, 54, ...?
