Find the nth term of the AP 1, 
, ….
To Find: nth term of the AP
Given: The series is 1, 
, 
, 
, …
a1=1, a2= 
and d= 
–1= 
(Where a=a1 is first term, a2 is second term, an is nth term and d is common difference of given AP)
Formula Used: an = a + (n - 1)d
an= a1 + (n - 1)( 
) = 1– (
) = 
=(
)
So the nth term of AP is equal to (
)
