Back

-5

Front

What is the recursive rule for the sequence 17, 10, 3, -4, -11...?

Front

What is the recursive rule for the sequence -5, -1, 3, 7, 11...?

Back

a_n=a_{(n-1)} + 4, a_1=-5

Front

Define an arithmetic sequence.

Back

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

Front

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

Back

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

Front

What is a geometric sequence?

Back

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 formula for the nth term of a geometric sequence?

Back

a_n = a_1 * r^{(n-1)}, where r is the common ratio.

Front

What is a recursive sequence?

Back

A sequence where each term is defined as a function of the preceding terms.
