Think Twice | Sum of first n odd numbers | Visual mathematics | @ThinkTwiceLtu | Uploaded July 2017 | Updated October 2024, 1 day ago.
Short animation about the sum of first n odd numbers.
here is an algebraic proof:
The first n odd natural numbers are 1, 3, 5, ... 2n-1. This forms an arithmetic progression with first term 1, common difference 2 and last term (2n-1).
The sum is given by S = 1+3+5+...+(2n-1).
Using S = n (First term + Last term)/2,
we get S = n (1+2n-1)/2,
which simplifies to S = n^2.
