Language is Fortran

1) Write a program in Fortran to generate the following sequence up to the nth term: 1*2 +2*4 +3*6+4*8+ 5*10+ ... The program should read a positive integer and then displays the first n terms of the sequences. The program should make sure the value of n is at least 2. It will ask the user repetitively for the correct input until user enters a valid number (n > 2). (10 points)
