Answer 2

Number of Integers Between -15 and 17

The number of integers located on the number line between -15 and 17 can be determined by finding the inclusive range of integers between these two numbers.

The inclusive range of integers between -15 and 17 is from -15 to 17, inclusive. This means that all integers from -15 to 17, including -15 and 17, are part of this range [[3]](https://library.sspu.edu.ua/wp-content/uploads/2021/11/appmo_117_2021.pdf).

Therefore, the number of integers between -15 and 17 is calculated as: Number of integers = (17 - (-15)) + 1 Number of integers = 17 - (-15) + 1 Number of integers = 17 + 15 + 1 Number of integers = 33

So, there are 33 integers located on the coordinate line between -15 and 17.

Sum of the Integers

The sum of these integers can be calculated by finding the sum of the first and last integers in the range and then using the formula for the sum of an arithmetic series.

The sum of the integers between -15 and 17 can be calculated using the formula: Sum = (n/2) * (first term + last term) where n is the number of terms, and the first and last terms are -15 and 17, respectively.

Substituting the values: Sum = (33/2) * (-15 + 17) Sum = (16.5) * (2) Sum = 33

Therefore, the sum of the integers located on the coordinate line between -15 and 17 is 33.
