Question

Write an algorithm and pseudocode to compute f(x)=1+x+x^2+x^3+....+x^n

Answer 1

Algorithm 
Start
        Declare variable n
        Declare variable x
        Get n from the user
        Get x from the user
        Declare variable sum=1
        for i  = 1 to n step 1
            Find sum = sum + x^i
        next
        Display sum 
End

Pseudocode 
Start
        Set n = 0
        Set x = 0
        Get n from the user
        Get x from the user
        Set sum = 1
        for i = 1 to n
            sum = sum + x^i
        Display sum 
End
