Find the indicated terms of the sequences whose nth terms are given by
(ii) an = (n2  4); a4 and a11
Solution :
To find a4, we have to apply 4 instead of n.
To find a11, we have to apply 11 instead of n.
Hi, Am Regina, a simple woman from the beautiful place, Kalakad, a village surrounded by lush green paddy fields. I love cooking.
an = (n2  4)
n = 4
a4 = (42  4)
a4 = (16  4)
= 12

an = (n2  4)
n = 11
a11 = (112  4)
a11 = (121  4)
= 117
