Data

Answer

-20

To find the mean (average) of 3 numbers, follow the step-by-step solution below.

Step 1 — Find the sum of all values

Add all values together:

-10 + -20 + -30 = -60

Step 2 — Divide the sum by the count (3)

The mean is the sum divided by how many values there are:

Mean = -60 ÷ 3 = -20

Mean = -20
