What is the median of the following numbers? 1, 2, 2, 8, 9, 14
sesenic [268]

Answer: 5

Step-by-step explanation: The median is the middle number in the data set when the data set is written from least to greatest.

Notice that our data set is already written from least to greatest.

1, 2, 2, 8, 9, 14

Notice that in this data set, there is no middle number directly because 2 and 8 fall directly in the middle. In this situation, we take the average of these two middle numbers and divide their sum by 2.

Since 2 and 8 are the numbers that appear in the middle, we add them.

2 + 8 gives us 10.

Now we divide 10 by 2 to get 5.

So the median of this data set is 5.

Add the first 12 terms of this sequence:<br> 15, 45, 135, 405, 1215, ...
UkoKoshka [18]

Answer:

Step-by-step explanation:

a₁ = 15

a₂/a₁ = 45/15 = 3

a₃/a₂ = 135/45 = 3

...

It is a geometric sequence with a common ratio r=3.

Sum of first 12 terms = a₁·(1-r¹²)/(1-r)

= 15·(1-3¹²)/(1-3)

= 15·(-531,441)/(-2)

= 3,985,800
