What integer does 2n - 1 represent when n = 5?

To determine the integer that 2n - 1 represents when n = 5, you first substitute 5 for n in the expression. The step is straightforward:

1. Substitute n with 5:

2n - 1 becomes 2(5) - 1.

2. Perform the multiplication:

2(5) equals 10.

3. Now, subtract 1 from that result:

10 - 1 equals 9.

Thus, when n = 5, the expression 2n - 1 evaluates to 9. This is why the answer is 9.
