Answer: an = 8 + -2(n - 1)
Explanation:
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 = 8
Common difference is the term - the previous consecutive term. Therefore,
d = 6 - 8 = 4 - 6 = - 2
We want to determine the equation for the nth term of the arithmetic sequence. It becomes
an = 8 + - 2(n - 1)
