(i) In this problem, we need to find the sum of all odd numbers lying between 0 and 50.
So, we know that the first odd number after 0 is 1 and the last odd number before 50 is 49.
Also, all these terms will form an A.P. with the common difference of 2.
First term (a) = 1
Last term (l) = 49
Common difference (d) = 2
So, here the first step is to find the total number of terms. Let us ...
