1: 5
2: 244

To find the mean add up all the numbers so
: 2+2+5+6+8+4+8+5=40. The divide by the amount of numbers there are 8 numbers so 40/8=5.
To find the median just put the numbers in order
131,154,204,207,244,244,263,274,276,288,289
then cross them out until your in the middle
So 244

Step-by-step explanation:

In this case, since $60.5 - 55 \neq 55 - 50$ , it has a common ratio.
