The formula for an arithmetic sequence is:
An = A1 + (n - 1)d
where An represents the nth term, A1 represents the first term, n represents the position of the term, and d represents the common difference between consecutive terms.
In this case, the first term (A1) is 8. The second term can be obtained by adding the common difference to the first term: A2 = 8 + d = 1.5. Solving for d, we find that d = -6.5.
Thus, the formula for the arithmetic sequence is:
An = 8 + (n - 1)(-6.5)
Which functions represent the arithmetic sequence 8,1.5,-5,-11.5
