Chapter 1.1, Problem 30PPSE

Solution

To Identify: The given pattern and calculate the next three numbers in the pattern.

The next three numbers in the pattern are $2500,12500$ and $62500$ .

Given information:

The pattern is: $4,20,100,500,\dots$

Calculation:

Given the pattern is, $4,20,100,500,\dots$

It can be seen from the pattern that the next number is $5$ times the previous number.

So, next three numbers are as follows:

  $\begin{array}{c}500\times 5=2500\\ 2500\times 5=12500\\ 12500\times 5=62500\end{array}$

Thus, next three numbers in the pattern are $2500,12500$ and $62500$ .
