Quizplus · Accepted Answer

The common difference in the sequence is -3 (subtracting 3 each time). The nth term of an arithmetic sequence is given by the formula a_n = a_1 + (n - 1)d, where a_1 is the first term, d is the common difference, and n is the term number. Plugging in the values: a_15 = -4 + (15 - 1)(-3) = -4 - 42 = -46.
