Chapter 4.7, Problem 16PPE

To determine

Pattern and next two term for the given sequence “99, 88, 77, 66, …..”

Answer to Problem 16PPE

The pattern is “Each next term is 11 less than the previous term”.

And next two terms are 55 and 66.

Explanation of Solution

Given:

The given sequence is,

99, 88, 77, 66, …..

Here,

  $\begin{array}{l}88-99=-11\\ 77-88=-11\\ 66=77=-11\end{array}$

So, the pattern followed in given sequence is

“Each next term is 11 less than the previous term”

So, the next two term will be

  $\begin{array}{l}66-11=55\\ 55-11=44\end{array}$
