Question

What is the next term in the sequence? 1,-3,9,-27

Answer 1

You have to multiply negative 3 each time !

Answer 2

Begin by studying the pattern.

Here, notice that 1 × -3 is equal to -3.

-3 × -3 is equal to 9.

9 × -3 is equal to -27.

Continuing the same pattern, -27 × -3 is equal to 1.

So the next term in the pattern is 81.

So, we multiply by -3 each time.
