A program to calculate and print the sum of the series 1;3;5;7;9.....21

Question

Please give the answer

Answer 1

Mujtaba Ali I have disliked your post because of two main reasons. They're as follows:

1. Your question is vague as the tag 'hallo' doesn't make any sense. Please specify the required language in the tag.

2. You haven't posted any attempt of yours; in fact, it seems like you won't be posting one any sooner as you're directly asking for the answer.

Try rectifying the two issues mentioned above and we'll be glad to help you. I hope that this helps. Happy coding!

Answer 2

use this formula lol
n/2(2a + (n - 1) d) = sum of the series
