Note
Firstly, The basic rule for divisibility by 4 is that if the number formed by the last two digits in a number is divisible by 4, the original number is divisible by 4
Secondly, If the last two digits end with 00 this is because 100 is divisible by 4 and so adding hundreds, thousands, etc. 4 can divide perfectly.
Given
The divisibility test successful 98942d is divisible by 4
[tex]\begin{gathered} 20 \\ 24 \\ 28 \\ \text{all divisible by 4} \end{gathered}[/tex]Therefore d can be
[tex]0\text{ or 4 or 8}[/tex]The final answer
d is either
0 or 4 or 8
