How would i write a variable to represent the sum of four consecutive numbers if the least number is p

Start with what we know: Our lowest number is and we want a sum, let's call that .

We know we want consecutive numbers and we want 4 of them. Numbers are consecutive if they come "one after another", that is to say: we can get from one to the other by adding or subtracting 1.

If we start with we can get consecutive numbers by repeatedly adding 1 (notice we aren't using the "or subtracting" part here because we know is our lowest number).

So: starting with , adding one over and over until we've got our four numbers we have:






And now we can write our sum:
