Question

Describe the pattern. Find the next three numbers. 15, 1.5, 0.15, 0.015,... Each number is times the previous number. The next three numbers are , , and .

Answer 1

0.0015

0.00015

0.000015

Explanation:

There are given a few numbers in sequence, which are 15, 1.5, 0.15, 0.015, ......

Now, we have to describe the pattern of this sequence.

Those numbers are in Geometric Sequence with first term 15 and common ration
`(1.5)/(15) = 0.1`.

Therefore, the next three terms of this geometric sequence will be (0.015 × 0.1) = 0.0015, (0.0015 × 0.1) = 0.00015, and (0.00015 × 0.1) = 0.000015.

The next three numbers are

0.0015

0.00015

0.000015 (Answer)
