Find the indicated terms of the sequences whose nth terms are given by
(i) an = 5n / (n + 2); a6 and a13
Solution :
To find a6, we have to apply 6 instead of n.
To find a13, we have to apply 13 instead of n.
an = 5n / (n + 2)
n = 6
a6 = 5(6)/(6 + 2)
= 30/8
a6 = 15/4
|
an = 5n / (n + 2)
n = 13
a13 = 5(13)/(13 + 2)
= 65/15
a13 = 13/3
