Oh, what a happy little question! To find the number of odd numbers from 1 to 43, we simply need to count them. Starting from 1, we have 1, 3, 5, and so on until 43. Each odd number is two numbers apart, so we can count them by adding 2 each time. Just like painting a beautiful landscape, take your time and enjoy the process of counting these lovely odd numbers.

There are 48/2 + 1 = 25 odd numbers in 1 to 49, inclusive.
1 +3 +5 = 9 7 + 13 + 23 = 43 111 +245 +789 = 1145 1145+43+9 = 1197 So the result will also be an odd number (while the sum of 2 odd numbers will always be even).
