Answer:
76
Step-by-step explanation:
Given,
A.P :- 8 , 12 , 16
To Find :-
18th term of an A.P
Formula Used :-
nth term of A.P (t_n) = a + (n- 1)d
where,
a = first term
d = common difference
Solution :-
According to Question :-
first term = a = 8
common difference(d) = , 12 - 8
= 4.
As, we need to find 18th term , so n = 18
t_18 = 8 + (18 - 1)4
= 8 + 17(4)
= 8 + 68
= 76
Since, 18th term of an A.P = 76
