Sum array of the increment of input values

I'm trying to write a sum array function that takes two input values. The first input value is added incrementally until it reaches the value of the second input. For example if the lowerLimit is '2' and the upperLimit is '5' the total sum would be 2 + (2+1) + (2+2) + (2+3) + (2+4) + (2+5) = 27. I've tried using the variable 'i' that is added to the lowerLimit and goes up incrementally until (i <= (upperLimit - lowerLimit) but I'm unsure of how to do write the sum array, or if a sum array is even the best way to approach this. Thanks for your help.

                var lowerLimit = parseInt(prompt("What number would you like to being with?"));
                if (isNaN(lowerLimit)) {
                    alert("That's not a number, please retry.");

                var equation = lowerLimit + (lowerLimit+i);

            }
            //ends document ready function

what is use of arrays? You can directly add them and give output without using arrays...

try this code:

var sum=lowerLimit; for(i=1; i<=upperLimit; i++){ sum += (lowerLimit+i); }

sorry there is a mistake in that code

var sum=lowerlimit;
for(i=1; i<=upperLimit; i++){
  sum += (lowerLimit+i);
}
