The general formula for the distance between two numbers x and y on the number line is |x-y|. Plugging 42 and 95 in for x and y, we get |42-95|=|-53|=53. Notice that it doesn't matter which order we plug the numbers in: if we plugged 95 in for x and 42 for y, we'd get |95-42|=|53|=53. So either way we do it, the distance is 53.
Half way between 36 and 42 is (36 + 42) ÷ 2 = 39.
Halfway between 42 and 82 is (42 + 82) ÷ 2 = 124 ÷ 2 = 62.
