I'm having a hard time completing task 2 of d. and e.
answer them.

Step-by-step explanation:

In part (d), we are shown how the sum of consecutive integers can be found.  The sum is:

S = n (x + y) / 2

where n is the number of integers, x is the first integer, and y is the last integer.

We want to use this formula to find the sum of the numbers 101-110.  We know there are 10 numbers between 101 and 110, so n = 10.

S = 10 (101 + 110) / 2

S = 1055

We used deductive reasoning to find the answer.
