Find an equation for the nth term of the arithmetic sequence. 8, 6, 4, 2, ...

Step-by-step explanation:

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

Tn = a + d (n - 1)

Where

a represents the first term of the sequence.

d represents the common difference (Common difference is the difference between a term and the previous consecutive term).

n represents the number of terms in the sequence.

From the information given,

a = 8

d = 6 - 8 = 4 - 6 = - 2

The equation for the nth term of the arithmetic sequence would be

Tn = 8 + - 2 (n - 1)
