How many odd numbers are between 1 through 99?

Answer 1

There are 49 odd numbers between 1 and 99. These numbers can be listed as 1, 3, 5, ..., 97, 99. The sequence of odd numbers from 1 to 99 forms an arithmetic series where the first term is 1, the last term is 99, and the common difference is 2. To find the count, you can use the formula for the nth term of an arithmetic sequence, which confirms there are 49 odd numbers in this range.
