There are 48/2 + 1 = 25 odd numbers in 1 to 49, inclusive.
49 is an odd number. All numbers ending in 1, 3, 5, 7, or 9 are odd numbers.
135791113151719212325272931333537394143454749.
1 + 3 + 5 + ... + 49 = ((49 + 1)/2)2 = 625
There are 50 odd numbers between 0 and 99. These numbers are 1, 3, 5, 7, and so on, up to 99. The sequence of odd numbers can be represented as 2n + 1, where n ranges from 0 to 49. Thus, the total count of odd numbers is 50.
The sum of 5 odd numbers must be odd and 100 is even. So there cannot be such a set.

The first seven odd numbers are 1, 3, 5, 7, 9, 11, and 13. To find their sum, you can add them together: 1 + 3 + 5 + 7 + 9 + 11 + 13 = 49. Therefore, the sum of the first seven odd numbers is 49.
It is not possible for five odd numbers to add up to 50 or any even number.
There are 50 odd numbers in the range from 1 to 99. This can be calculated by dividing the total range (99 - 1 + 1 = 99) by 2, as every other number in the range is odd. Therefore, 99 / 2 = 49.5, but since we are dealing with whole numbers, there are 50 odd numbers in the range from 1 to 99.
There are 15 prime numbers between 1 and 49
They are: 1+3+5+7+9+11+13 = 49
All the numbers above 2 that are the squares of odd primes have exactly 3 factors: 1, the odd prime, and the odd prime squared. 4, 9, 25, 49, 81, 121,...
