Determine whether each sequence is anthmetic or geometrie Sequence 1: -10, 20, -40,80, ... Sequence 2: 15, -5, -25,-45,

Sequence 1- Geometric Progression

Sequence 2 - Geometric Progression

Step-by-step explanation:

Arithmetic progression

An arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant.

The general form is an = d (n - 1) + a1 where a1 is the starting number of teh order

Geometric progression

A geometric progression, also known as a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

The general form is  an = a1r-1 where r is the ratio

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
