Write a program that calculates the sum of N integers in a sequence.

**Background**

An integer sequence has *N* integers, with a starting value
*a*, and a constant difference *d* between 2
integers.

For example: the sequence 3, 9, 15, 21
has
N = 4, a = 3, d = 6

and the sequence 1, 2, 3, 4, 5, 6, 7
has N = 7, a = 1, d = 1

The sum *S* of all *N* integers is calculated as:
*S = N(2a + (N-1)d) /* 2

**Requirements**

1. Prompt the user for the *N*,
*a*, and *d* values, in that order.

- You can expect that the user will give you N,
*a*, and*d*values that are between 1 and 100, so there's no error checking needed. - Given that 100 is the max value of all input, use the
*appropriate data type*and the*register size*that can store the maximum output value, but*do not use the largest possible data size*. - Use 32bit registers except esp

2. Calculate the sum, using the given formula.

- Be efficient with your code for the calculation (Refer to the class notes for suggestions).

3. Print the values of *N*,
*a*, *d*, and sum on one line of output. See sample
output.

4. Do not declare and use any memory variable, except for text
strings.

- The text strings for the prompts and the output text can be defined in the .data section, but all user input and calculation results should be in registers.

**Test**

Sample program output:

Enter the number of integers:
90

Enter the start integer: 3

Enter the difference between
integers: 1

N = 90, a = 3, d = 1, sum = 4275
