Exercise 2 Page 410

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

1, - 2, 4, - 8, 16, and - 32

Practice makes perfect

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

f(n)= (- 2)^(n-1) To do so, we will construct a table.

n	f(n)= (- 2)^(n-1)	f(n)
1	f( 1)=(- 2)^(1-1)	1
2	f( 2)=(- 2)^(2-1)	- 2
3	f( 3)=(- 2)^(3-1)	4
4	f( 4)=(- 2)^(4-1)	- 8
5	f( 5)=(- 2)^(5-1)	16
6	f( 6)=(- 2)^(6-1)	- 32

The first 6 terms of this explicit sequence are 1, - 2, 4, - 8, 16, and - 32.
