Use mathematical induction to prove that

$4|(9^n-5^n)$

for all $n=0,1,2,3,$dots

Notes:

The solution must include all the necessary steps.

The quality of writing will be among the factors in marking.

The solution is to be included in your Q$3$ solution template before Q$3$ starts. It is

better to change the file name prefix of the solution template file to make it relevant

to the context of the quiz and your SID. For example, qm$\_$sid.docx, where $m=$

$1,2,3,$dots, as appropriate, and sid is your SID.
