Sequences: Do Now

a_n = a_1 + (n+1)d

a_n = a_1 + (n-1)c

a_n = a_1 + (n-1)d

a_n = a_1 - (n-1)d

The common ratio in a geometric sequence changes with each term

The common ratio in a geometric sequence is equal to the sum of the terms

The common ratio between consecutive terms in a geometric sequence is a constant value.

The common ratio in a geometric sequence is always negative

a_n = a_1 + r^(n-1)

a_n = a_1 * r^(n-1)

a_n = a_1 + r^n

a_n = a_1 * r^n

An explicit formula and a recursive formula both provide the nth term directly.

An explicit formula and a recursive formula both define the nth term based on previous terms.

An explicit formula provides the nth term directly, while a recursive formula defines the nth term based on previous terms.
