    Answer: an = 8 + - 2 (n - 1)

    Step-by-step 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)
