sum of a series does not having sequence

Let’s sum the following series

 Here we see that there is no sequence in the series. In this case the solution is

1234567890

              Sum=0.0               

               Do k=1,6

               Write(*,*) 'Enter the value of x'

               Read(*,*) x

               Sum=sum+x

               End do

               Write(*,*) 'The sum of the above series is =',sum

               End 

              (Here the result is 48.) . Just copy this program and paste this in your Force2.0 and run . Put the values of x that is 5 then press enter then put 9 and in the same way put 3,10,7 and 14 and press enter . The output will be (The sum of above series is =  48.)

Let’s try yourself

Here do k=1,5

As the series  have 5 values
