Exercise 10 Page 414

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

- 1, - 4, - 9, - 16, - 25, and - 36

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 To do so, we will construct a table.

n	a_n=- n^2	a_n
1	a_1=- 1^2	- 1
2	a_2=- 2^2	- 4
3	a_3=- 3^2	- 9
4	a_4=- 4^2	- 16
5	a_5=- 5^2	- 25
6	a_6=- 6^2	- 36

The first 6 terms of this explicit sequence are - 1, - 4, - 9, - 16, - 25, and - 36.
