Exercise 2 Page 155

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

12, 2, 92, and 8

Practice makes perfect

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

n f(n)=n^2/2 f(n)
1 f( 1)=1^2/2 1/2
2 f( 2)=2^2/2 2
3 f( 3)=3^2/2 9/2
4 f( 4)=4^2/2 8

The first 4 terms of this explicit sequence are 12, 2, 92, and 8.
