Evaluate 12sigma n=3 -5n-1

  -385

Step-by-step explanation:

Perhaps you want the sum of 10 terms of the arithmetic sequence ...

  -16, -21, -26, ..., -61

The sum of any arithmetic sequence is the average term multiplied by the number of terms. The average term is the average of the first and last terms. Here, that is ...

  ((-16-61)/2)(10) = -385
