Question

What the meaning of geometric sequence?​

Answer 1

Below.

Explanation:

It is a sequence of numbers with a common ratio. That is, each term after the first is obtained by multiplying the previous one by the common ratio.

Examples:

2, 6, 18, 54 ... is a geometrics sequence with common ratio 3.

1, 1/2, 1/4, 1/8 ... has a common ratio of 1/2.

-1, 1, -1, 1, -1 ... has a common ratio of -1.

The nth term of a geometric sequence is given by

a r^(n-1) where a = first term and r = common ratio.

Answer 2

What is the meaning of geometric sequence?

Explanation:

A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value. Its general term is. a n= a 1 r n – 1. The value r is called the common ratio. It is found by taking any term in the sequence and dividing it by its preceding term.
