8.25 is halfway between them.
70-10=60. 60/2=30. 10+30 or 70-30=40. Answer 40
Halfway between any two multiples of ten is always a multiple of five because each multiple of ten is also a multiple of five. For example, if you take the multiples of ten 20 and 30, their halfway point is 25, which is a multiple of five. This holds true for any pair of multiples of ten, as the average will always yield a number divisible by five.
