What is in the middle of 50 and 28 (numbers)

A good way to find the mean ( averag/ middle number) is to add the lowest and highest number, then divide by two.

so, you would want to add 50 and 28 together. You get 78, now you want to dived by 2. you get 39 as the middle number.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
