What is mean median mode

Step-by-step explanation:

mean- add up all numbers and divide by how many numbers there are

median- the middle number out of the list of numbers

mode- the number you see most often

- Mean is the total of all the values, divided by the number of values
- Median is the middle number in a list of numbers ordered from lowest to highest
- Mode is the value that appears most often in a set of data

The sequence is A(n) = 27*(1.5)^(n-1)

Step-by-step explanation:

First, we need to see which type of sequence we have:

Differences:

27 - 18 = 9

18 - 12 = 6

the differences are different, let's try with the ratios.

27/18 = 1.5

18/12 = 1.5

12/8 = 1.5

So we have that this ratio is constant, then the sequence can be:

A(n) = 27*(1.5)^(n-1)

For n an integger number

where:

A(0) = 27*1.5^0 = 27

A(1) = 27*1.5^1 = 18

A(2) = 27*1.5^2 = 12

A(3) = 27*1.5^3 = 8
