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

2.

FLASHCARD QUESTION

Front

What is the formula for the nth term of an arithmetic sequence?

Back

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

FLASHCARD QUESTION

Front

Given the sequence 6, 11, 16, 21, what is the common difference?

Back

The common difference is 5.

4.

FLASHCARD QUESTION

Front

How do you find the 25th term of an arithmetic sequence?

Back

Use the formula a_n = a_1 + (n-1)d. For a_1 = 5 and d = 0.5, a_25 = 5 + (25-1)0.5 = 17.

FLASHCARD QUESTION

Front

What is a geometric sequence?

Back

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

6.

FLASHCARD QUESTION

Front

What is the formula for the nth term of a geometric sequence?

Back

The formula is a_n = a_1 * r^(n-1), where a_1 is the first term and r is the common ratio.
