Answer: The last one
Step-by-step explanation:
I think this because the graph starts from H the number of hours studied and when u add the numbers and divide them up which gives you the equation 65 + 50 . Any questions please text me. Have a nice day.
The answer to this equation is 48.
The common difference is x
the first term is x+1
a_8 = x+1 + x(8-1) = x+1 + 7x = 8x + 1
76.25 is the answer because 1525 divided by 20 equals 76.25
Can u just post the whole question or elaborate further
