For the following code segment calculate the total number of additions and subtractions taking place for a positive value of x For a := 3 to x

Question

Need help with finding the answer to this math problem.

 

For a := 3 to x
Ans = Ans + 3a – 4x + 4
Next a

Answer 1

But no code segment is shown, so how can we answer the question?  Obviously the value of x would have to be a known integer, also, causing the  the body of code controlled in the loop to be performed (x-2) times.
