Question

If the set is finite (0,1,2,3,...114) determine how many elements are in the set.

Answer 1

There are 115 numbers between 0 and 114.

In fact, in general, there are
`b-a+1` integers between
`a` and
`b`, if both
`a` and
`b` are integers and
`a \leq b`.

So, in your case, there are
`114-0+1 = 115` numbers in the set.
