Exercise 11 Page 414

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

- 4, - 1, 4, 11, 20, and 31

Practice makes perfect

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

a_n= n^2-5 To do so we will construct a table.

n	a_n=n^2-5	a_n
1	a_1= 1^2-5	- 4
2	a_2= 2^2-5	- 1
3	a_3= 3^2-5	4
4	a_4= 4^2-5	11
5	a_5= 5^2-5	20
6	a_6= 6^2-5	31

The first 6 terms of this explicit sequence are - 4, - 1, 4, 11, 20, and 31.
