The answer would be 61. First, if you are trying to figure out the pattern. You must subtract the
second number with the first then fourth number with the fifth and so
on, you get.
73 minus 66 equals 7.
21 minus 13 equals 8.
XX minus 52 equals x.
20 minus 10 equals 10.
Basing on the pattern of the set of numbers, x will equal 9, To get this you must do 52 and 9 which will equal 61.
If you mean average, then it's quite simple.
Usually when you want to find the average of something, you add them up all together and divide by how many there are.
For example, the numbers:
12, 69, 35, 67, and 2.
Steps:
1.) Add them. 12 + 69 + 35 + 67 + 2 = 185
2.) 185 divided by 5.
3.) Answer: 37
I believe the answer is C. It is the only one that makes sense
This function, y=8x+7 is linear with a slope (m) =8.
Any other function with slope m = 8 could be the other equation
Example:
y=8x+10
y=8x-5/3
y=8x+10,000
etc.
In short there are an infinity of function
