To count consecutive integers, use the following formula:
biggest - smallest + 1.

Number of integers between 51 and 107, inclusive:
biggest - smallest + 1 = 107 - 51 + 1 = 57.

The correct answer is D.

When we are including both the first number and the last number, we must add 1 to their difference. Thus, the number of integers between 51 and 107, inclusive, is 107 - 51 + 1 = 57.

Answer: D

The integers between 51 and 107, inclusive, are the values in the range from 50 < V <= 107.
Therefore the quantity of these integers is 107-50 = 57 [D]

Hi lheiannie07,
Let's take a look at your question.

To find the number of integers between any two given integers, inclusive, we use the formula:
Highest Number - Lowest Number + 1
= 107 - 51 + 1
= 57

Therefore, Option D is correct.

Hope it helps.
I am available if you'd like any follow up.
