Question

in general, for an integer a, state the values of and . compute . select the correct choice below and, if necessary, fill in the answer box to complete your choice.

Answer 1

For an integer a, the values of a+1 and a-1 can be determined by adding or subtracting 1 from the value of a.

Step-by-step explanation:

In general, for an integer a, the values of a+1 and a-1 can be determined. For example, if a = 5, then a+1 = 6 and a-1 = 4.

To compute a+1, simply add 1 to the value of a. To compute a-1, subtract 1 from the value of a.

For example, if a = 10, then a+1 = 11 and a-1 = 9.
