Halfway Between 20 and 835

When you ask "What number is halfway between 20 and 835?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=835.

Halfway Between Line

To find the number halfway between 20 and 835, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 835 into our formula, we get:

(20 + 835)/2 = 427.5

Thus, the number halfway between 20 and 835 is 427.5.

To check that our answer is correct, we subtract 20 from 427.5 and subtract 427.5 from 835 and compare the two numbers:

427.5 - 20 = 407.5
835 - 427.5 = 407.5

As you can see, the halfway number is 407.5 higher than 20 and 407.5 lower than 835. Therefore, our halfway between answer of 427.5 above is correct.
