Keep in mind that 'd' represents the common difference for an arithmetic sequence. Which means to find the value of a_32, we can use the arithmetic sequence formula a_n = a_1 + (n - 1)*d

SOLUTION: a_32 = 189 (or the value of a_sub32 is 189)

Keep in mind that for an arithmetic sequence formula, 'a1' represents the first term in a sequence, 'd' is the common difference, and 'n' is the index value taken from 'n'. Was there any questions you had over the work shown for your problem?
