Answer:
the common difference of the sequence is 
Step-by-step explanation:
A sequence of numbers is said to be in arithmetic progression of each term of the sequence has same common difference.
Now, here first term a1 = 1/4
Second term a2 = 5/16
Third term a3 = 3/8
Now, Common difference (d) = a2 - a1 = a3 - a2
Now, a2 - a1 = 
Now, a3 - a2 = 
Hence, the common difference of the sequence is 
Answer:
(86.2,0) is the x-intercept.
Step-by-step explanation:
You can use the slope formula to figure this one out:
Just use two of the points on the table, any of them will work:


Now you have the slope of the equation, now using the y-intercept equation you can substitute the variables for point of the table and the new slope.:

Now just solve for b to get the y intercept:

Now you have the y-intercept so you just have to plug in 0 to the y spot and it will calculate the x-intercept.

And that's the x-intercept.
