Arithmetic sequences have a pattern of numbers that are positive and negative but are a constant amount.
In this case the answer is A.
They square root of 0.64 is 0.8
The answer is 10x - 1380m + z
The slope for 1 is 3/9 or 1/3 so the equation can be y-0=1/3(x-0)
and for 2 the slope is -2/-8 or 1/4 and the equation is y-0=1/4(x-0)
In PEMDAS you do parentheses first
(32-20) equals 12
Now you divide
12/4 equals 3
The answer is 3
