How many multiples of 2 exist between -10 and 10, not inclusive?

A. 7
B. 8
C. 9
D. 10
E. 11

Step 1: Find the effective inclusive range.

-10 and 10 are not included so we need to cut those off, the inclusive range is all multiples of 2 from -8 to 8.

Step 2: Plug in the formula.

\(\frac{Max - Min }{ StepSize} + 1\) = \(\frac{8 - (-8)}{2} + 1\) = 8 + 1 = 9.

Ans: C
