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
