Exercise 12 Page 414

Substitute values for n=1, 2, 3, 4, 5, and 6 to find the first 6 terms.

16, 25, 36, 49, 64, and 81

Practice makes perfect

We are given an explicit rule of a sequence and are asked to find the first 6 terms.

a_n= (n+3)^2 To do so we will construct a table.

n	a_n=(n+3)^2	a_n
1	a_1=( 1+3)^2	16
2	a_2=( 2+3)^2	25
3	a_3=( 3+3)^2	36
4	a_4=( 4+3)^2	49
5	a_5=( 5+3)^2	64
6	a_6=( 6+3)^2	81

The first 6 terms of this explicit sequence are 16, 25, 36, 49, 64, and 81.
