What is the median of this data set? {10, 15, 12, 6, 2}

Hello there!

Median is the middle of the data set.

So, first we have to arrange it into proper numerical order (least to greatest).

2,6,10,12,15

Then, we look for the middle number.

It is 10, therefore 10 would be the median of this data set.

10

Step-by-step explanation:

{10, 15, 12, 6, 2}

Put the set in order from smallest to largest

{2,6,10, 12, 15}

The median is the middle number

{2,6    ,10,      12, 15}

10 is the median

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
