Answer 30

That's just the mean.

Now we find the difference of the numbers from the mean.

9, 12, 18, 20, 26, 35

20 - 9 = ?
20 - 12 = ?
20 - 18 = ?
20 - 20 = ?
26 - 20 = ?
35 - 20 = ?

Answer 41

20 - 9 = 11
20 - 12 = 8
20 - 18 = 2
20 - 20 = 0
26 - 20 = 6
35 - 20 = 15

Add them up and divide by 6.

\(\sf \dfrac{11 + 8 + 2 + 0 + 6 + 15}{6}\)

Answer 42

Oh, you're right..42..now divide by 6.
