Answer:
last option
Step-by-step explanation:
We know that a₁ (or the first term) = 4 so we can rule out the second and third options. d (or the common difference) = 8 (because 4 + 8 = 12, 12 + 8 = 20 and so on) so our answer is the last option.
They are the came length. And are like mirrored.
(x^2)+4x-12=48
I Hope this is what you were looking for. If it isn't this just plug it in
x=6
29 + 33 = 62
6 + 7 > 12
number one is 33
number two is d = 7
x = 960
x=√{576×(576+1024)}
or, x = √(576×1600)
or, x = √576×√1600
or, x = 24×40
or, x = 960
