Find an equation for the nth term of the arithmetic sequence.

-17, -13, -9, -5, ...


an = -17 + 4(n + 2)

an = -17 x 4(n - 1)

an = -17 + 4(n - 1)

an = -17 + 4(n + 1)

Answer: an = - 17 + 4(n - 1)

Explanation:

In an arithmetic sequence, the consecutive terms differ by a common difference.

The formula for determining the nth term of an arithmetic sequence is expressed as

an = a + d(n - 1)

Where

a represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

From the information given,

a = - 17

d = - 13 - - 17 = - 9 - - 13 = 4

Therefore, the equation for the nth term of the arithmetic sequence is

an = - 17 + 4(n - 1)
