Step-by-step explanation:
<u>Arithmetic sequence</u>:-
Step1:
Given sequence is 
Above sequence taking numerator terms
3,6,9,12,15 are in arithmetic progression
First term a= 3 and difference d = 3
now n t h term of given sequence is

now substitute a =3 and d=3

Step2:-
Above sequence taking denominator
4,5,6,7,8...
here a=4 and d=1



Final answer is the general term of given sequence is
