# Find the nth term

Formula Used.

dn = an + 1 – an

an = a + (n–1)d

In the above sequence,

a = ;

d1 = a2–a1 = = d2 = a3–a2 = = d3 = a4–a3 = = The difference in sequence is same and comes to be ( ).

The above sequence is A.P

The nth term of A.P is an = a + (n–1)d

an = a + (n–1)d = + (n–1)( )

= = 1 + n
