1 answer:
9514 1404 393
Answer:
A, C
Step-by-step explanation:
The given ratio can be reduced by removing a factor of 2 from each element.
8 : 6 = 4 : 3 . . . . matches A
It can be put in other forms by multiplying each element by the same factor. Using a factor of 2 on the original ratio values, we get ...
8 : 6 = 16 : 12 . . matches C
__
Any ratio that doesn't reduce to the integer ratio 4 : 3 is not equivalent. The ratio with elements reversed (3:4) is not equivalent.

Answer:
an = 4/3n - 13/3.
Step-by-step explanation:
The first term is a1,
a24 = a1 + 23d
83/3 = a1 + 4/3* 23
a1 = 83/3 - 92/3
a1 = -9/3 = -3.
So the nth term an = -3 + 4/3(n - 1)
an = -3 + 4/3 n - 4/3
an = 4/3n - 13/3
