Answer:
The 3rd term is 18.
Given:
nth term an A.P. is 5n+3
To find:
3rd term of A.P.
Step-by-step explanation:
Hints-
Arithmetic progression:
It is series, in which the next term is obtained by adding constant number called 'common difference' in the previous term.
General term (Tₙ) = a + (n - 1)d
where a is first term, n is no. of term and d is common difference.
It is given that,
nth term of A.P. = 5n + 3
where, n is no.of term
so,
3rd term will be,
put 3 in place of n
⇒ 5n + 3
⇒ 5(3) + 3
⇒ 15 + 3
⇒ 18
Hence, the 3rd term is 18.
