Which of the following numbers is NOT divisible by 2?

A number is considered divisible by 2 if it is an even number, meaning it ends in 0, 2, 4, 6, or 8. In examining the provided options, the number 97 is the only one that ends in 7, which is an odd digit. Consequently, it cannot be evenly divided by 2.

In contrast, the other numbers listed—154, 132, and 60—each end in even digits (4, 2, and 0, respectively), confirming that they are even and therefore divisible by 2. This characteristic forms the basis for determining which numbers can or cannot be evenly divided by 2.
