Exercise 1 Page 154

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

- 3, 0, 5, and 12

Practice makes perfect

We are given an explicit rule of a sequence and are asked to find the first 4 terms.
f(n)=n^2 - 4 To do so, we will construct a table.

n	f(n)=n^2 - 4	f(n)
1	f( 1)= 1^2-4	-3
2	f( 2)= 2^2-4	0
3	f( 3)= 3^2-4	5
4	f( 4)= 4^2-4	12

The first 4 terms of this explicit sequence are - 3, 0, 5, and 12.
