Answer:
B
Step-by-step explanation:
When you are solving these kinds of problems, it's always best to start with getting rid of the decimal/fraction.

We can actually solve for a.
2/3*3=6/3=2
(15+2a=-5)
a=-10
(15+(-20)=-5)
TRUE
a=10 (I think)
A. 2(x+14) = 42
(2x = 14
x = 7
2(7) + 2(14) = 14 + 28 = 42)
Aritmetic has a common difference
-27 to -12 is a difference of 15
-12 to 3 is a difference of 15
an=a1+d(n-1)
a1=first term
d=common difference
fist term is -27
common difference is 15
an=-27+15(n-1)
84th term is n=84
a84=-27+15(84-1)
a84=-27+15(83)
a84=-27+1245
a84=1218
the 84th term is 1218
