PROGRESSION SERIES

 G.P Series Enter the Number( i) Enter'N' Value of Number i Enter Common Ratio (d) Find 1st Number of G.P (a) Enter N value of 'N'th Number Find Nth Number Find Sum Find Geometric Mean Find Arithmetic Mean
In Geometric Progression i.e G.P Series,l= nth term=a*dn-1
sum=(d*l-a)/d-1

 Sum of N successive Integers Lower Limit- aHigher Limit- b a < b Enter Lower Lt( a) Enter Higher Lt (b) Find Sum Find SUM of squares Find Square of SUM Find Sum of cubes
For n Natural Numbers starting from 1
sum=n(n+1)/2
sum of square=n(n+1)(n+2)/6
sum of cubes=(1/4)*(n^2)*(n+1)^2

1+3+5+....+(2n-1)=n2

2+4+6+....+2n=n(n+1)

H.P Series(Harmonic Progression)

 H.P Series Enter the Number( number) Enter no. of terms 'n' Enter Common Ratio (r) Find sum

********

 A.P Series Enter the Number( i) Enter'N' Value of Number i Enter Common Difference (d) Find 1st Number of A.P (a) Enter N value of 'N'th Number Find Nth Number Find Sum Find Arithmetic Mean
In Arithmetic Progression i.e A.P Series, nth term=a+(n-1)d
sum=n/2[2a+(n-1)d]
