Answer:
See below
Step-by-step explanation:
We shall prove that for all 
. This tells us that 3 divides 4^n+5 with a remainder of zero.
If we let 
, then we have 
, and evidently, 
.
Assume that 
is divisible by 
for 
. Then, by this assumption, 
.
Now, let 
. Then:
Since 
, we may conclude, by the axiom of induction, that the property holds for all 
.
