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

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
