Find the general, or n^th, term of the arithmetic sequence given the first term a₁ = -7 and the common difference d = -2. A) a_n = -5n - 2 B) a_n = 5n - 2 C) a_n = -2n - 5 D) a_n = -7n + -2

Question

Quizplus · Accepted Answer

The general term of an arithmetic sequence is given by a_n = a₁ + (n-1)d. Substituting a₁ = -7 and d = -2, we get a_n = -7 + (n-1)(-2) = -7 - 2n + 2 = -2n - 5.
