18,23,28,33,...

#1 is 18

#2 is 23

A difference of '5'

Hence we can write '5n + x = 18

Where 'n' equals '1'

Hence 5(1) + x = 18

5 + x = 18

Hence x = 18 - 5 = 13

So nth term is 5n + 13

NB Verification; does it work for the 4th term

5(4)+ 13 =

20 + 13 = 33

Which is true from above list.

The 'n'th term is [ 13 + 5n ].
