Given that the number ` 59142 a ` is divisible by 4, where `a` is a digit, what are the possible values of `a` ?

Explanation

To determine the possible values of the digit \( a \) in the number \( 59142a \) such that it is divisible by 4, we need to focus on the last two digits of the number, which are \( 2a \). A number is divisible by 4 if the number formed by its last two digits is divisible by 4.

### Step-by-Step Solution:

1. **Identify the last two digits**: The last two digits of the number \( 59142a \) are \( 2a \).

2. **Set up the divisibility condition**: For \( 2a \) to be divisible by 4, we need to find values of \( a \) such that \( 2a \) is a multiple of 4.
