Question

How many integers lie between_15and+15?

Answer 1

30 integers lie b/W -15 AND +15

Answer 2

Answer: Total number of integers is 29.

Step-by-step explanation: To find the numbers of integers between any two given integer, either we need to write down all the integers lying between them or we can apply the formula-

Number of integers between a and b (b>a) = b-a-1.

Given integers are -15 and +15, ie.,  a = -15  and  b = 15.

All the integers lying between -15 and +15 are  -14, -13, -12, -11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14. Thus, there are 29 integers.

Or, applying the formula, we get, No. of integers = 15-(-15)-1 = 29.

Thus, the answer is 29.
