Which term of the AP is 3?

Answer :

In the given AP, the first term = a = 5/6

Common difference = d = 1 - 5/6 = 1/6


To find: place of the term 3.


So, let an = 3


Since, we know that


an = a + (n - 1) × d


3 = (5/6) + (n - 1) × (1/6)


3 - (5/6) = (n - 1) × (1/6)


13/6 = (n - 1) × (1/6)


13 = n - 1


n = 13 + 1


n = 14


14th term of the AP is 3.
