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.
Halfway between any two multiples of 10 is indeed a multiple of five because the average of two multiples of 10 will always yield a result that is a multiple of 10. For example, the halfway point between 20 and 30 is 25, which is a multiple of five. More generally, since multiples of 10 can be expressed as (10n) and (10m), their average ((10n + 10m)/2) simplifies to (5(n + m)), confirming that the result is a multiple of five.
