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 = -385
