Chapter 11: Q. 280 (page 1069)

In the following exercises, determine if the sequence is geometric, and if so, indicate the common ratio.
$3, 12, 48, 192, 768, 3072, . . .$

Short Answer

Expert verified

The sequence is geometric and the common ratio is $4$ .

Step by step solution

Step 1. Given and explanation.

We have $3, 12, 48, 192, 768, 3072, . . .$
Geometric sequence is a ratio where the difference between the two continuous terms is always the same. This ratio is called common difference.
So to determine whether it is a geometric sequence or not, we need to calculate the ratio.

Step 2. Determining the ratio.

We have $3, 12, 48, 192, 768, 3072, . . .$
Ratio can be calculated as -

$\frac{12}{3} = 4$
$\frac{48}{12} = 4$
$\frac{192}{48} = 4$
$\frac{768}{192} = 4$
$\frac{3072}{768} = 4$

As we can see that the ratio is the same in every term, we conclude that the sequence is geometric with common ratio as $4$ .
