Question

A equivalent or odd number between 90 and 180

Answer 1

An odd number between 90 and 180 is 91

Answer 2

That means from 80 to 90, there are 5 odd numbers.

That also means, in between 10 numbers, there are 5 odd numbers.

It's fair enough to believe now that in the next 20 numbers—80 to 100—there will be 10 odd numbers.

Another pattern.

And the conclusion: from 80 to 180, there are 100 numbers. Therefore, There Will Be 50 Odd Numbers.

There are 50 odd numbers between 80 and 180.
