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.
