What is the 27th term of the A.P 3, 7, 11, ................ ?
111
107
103
130
This is an arithmetic progression, where first term (a) is 3, an there is a common difference (d) = +4
nth term for an AP generally is
a + (n - 1)d
In this case it is
3 + (n-1).4 = 3 + 4n - 4 = 4n - 1
So, 27th term = 4 x 27 - 1 = 107
