Find the nh term of the arithmetic sequence whose initial te
Find the nh term of the arithmetic sequence whose initial term is a, and common difference is d. What is the fifty second term Enter the formula for the nth term of this arithmetic series. Use parentheses as necessary Now, enter the value of the fty-second term of the sequence 52
Solution
a1 = 9, d = -7
an = a1 + (n - 1)*d = 9 + (n - 1)*(-7) = 9 - 7n + 7 = 16 - 7n
a52 = 16 - 7*52 = 16 - 364 = -348
