The correct answer for the question that is being presented above is this one: "B. -385." Evaluate the summation of negative 5 n minus 1, from n equals 3 to 12 equals B. -385
-5n - 1 where n = 3 to 12.
n = 3 = -16
n = 4 = -21
n = 5 = -26
n = 6 = -31
n = 7 = -36
n = 8 = -41
n = 9 = -46
n = 10 = -51
n =11 = -56
n = 12 = -61
Total = B. -385
