Flow chart for To read in two numbers x and n and then compute the sum of this geometric progression 1+x+x2+x3+……….+xn

In this program we have to read the two numbers and the calculate the sum of this geometric progression in above mention .





Output:

1.Enter the values for x and n:2 3
Value is valid Sum of series=15

2.Enter the values for x and n:4 9
Value is valid Sum of series=21845
  3.Enter the values for x and n:01
 Value is not valid

Conclusion: the program is error free
