Solution :-
1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23 + 25
All the Numbers here are Consecutive Odd Numbers starting from 1...
When We have find the Sum of 'n' Consecutive Odd Numbers starting from 1 , Count the Number of Odd number and Square it.
i.e. Sum of 'n' Consecutive Odd Numbers starting from 1 = n²
Here, n = 13
So, Sum of '13' Consecutive Odd Numbers starting from 1 = 13² = 169
i.e. 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23 + 25 = 169
