Answer 1

Interesting problem. But where are the instructions?

Answer 2

you're suppose to make a linear equation out of it. I myself in fact need help with this question

Answer 3

Think of what the term 'mean" signifies in Math.
Just for practice, find the means of

1) 49 29 38
and
2) 92 87 90 88 88 98

Also, if x is an integer, what's the next consecutive integer? The next one? How do you represent these?
