Answer 1

Answer:

Hope this helps

Step-by-step explanation:

Basically, N is of the form 5k+3 where k is an integer!

(This is because, it leaves a remainder 3 when divided by 5)

Now, put k=0,1,2,3…..

AND BOOOOOOOOOOOOM! There you are!

k=0 => 3 => Ones digit is 3,

k=1 => 8 => Ones digit is 8,

k=2 => 13 => Ones digit is 3,

k=3 => 18 => Ones digit is 3,

k=4 => 23 => Ones digit is 8,

k=5 => 28 => Ones digit is 3.

We see that the pattern repeats! So, the ones digit is either 3 or 8.
