Question

What kind of sequence is this? 36, 144, 432, -864, ..

Answer 1

Answer:

A Geometric sequence with common ratio 3

Step-by-step explanation:

A sequence of number is called Geometric sequence if the first number is being multiplied with a constant to get the rest of the numbers

ratio between 2 adjacent numbers in a sequence will be a constant and is called common ratio.

in the given sequence the ratio between any pair of adjacent numbers is 3.

∵ this is a geometric sequence with common ratio 3
