Formulas of Number Series
- 1 + 2 + 3 + 4 + 5 + … + n = n(n + 1)/2
- (12 + 22 + 32 + ….. + n2) = n ( n + 1 ) (2n + 1) / 6
- (13 + 23 + 33 + ….. + n3) = (n(n + 1)/ 2)2
- Sum of first n odd numbers = n2
- Sum of first n even numbers = n (n + 1)
- (a + b)(a – b) = (a2 – b2)
- (a + b)2 = (a2 + b2 + 2ab)
- (a – b)2 = (a2 + b2 – 2ab)
- (a + b + c)2 = a2 + b2 + c2 + 2(ab + bc + ca)
- (a3 + b3) = (a + b)(a2 – ab + b2)
- (a3 – b3) = (a – b)(a2 + ab + b2)
- (a3 + b3 + c3 – 3abc) = (a + b + c)(a2 + b2 + c2 – ab – bc – ac)
- When a + b + c = 0, then a3 + b3 + c3 = 3abc
Power, Surds and Indices Important Formula’s
- am x an = am+n
- am / an = am-n
- (am)n = amxn
- ao = 1
- a-m = 1/ am
- 1/a-m = am
