Exercise 6 Page 604

Substitute n=1,2,3,4,5 in the given formula.

1, - 1, - 3, - 5,- 7

Practice makes perfect
We are given an explicit rule of a sequence and are asked to find the first five terms.

a_n= - 2n +3 To do so, we will construct a table of values.

n a_n=- 2n +3 a_n
1 a_1=- 2 ( 1) +3 1
2 a_2=- 2 ( 2) +3 - 1
3 a_3=- 2 ( 3) +3 - 3
4 a_4=- 2 ( 4) +3 - 5
5 a_5=- 2 ( 5) +3 - 7

The first five terms of this sequence are 1, - 1, - 3, - 5, and - 7.
