HOW TO FIND SUM OF SPECIAL SERIES
Here we study some common special series like
(i) Sum of first ‘n’ natural numbers
1 + 2 + 3 + ............ + n = n(n + 1)/2
(ii) Sum of first ‘n’ odd natural numbers.
1 + 3 + 5 + ............ + (2n-1) = n2
(iii) Sum of squares of first ‘n’ natural numbers.
12 + 22 + 32 + ..... |
