The nth term is (presuming the denominator on the first is a typo)

The ratio of successive terms is

The limit is -1/3, absolute value less than 1, so the series converges. It has a sum -- that's what converges means.
The answer is C.
Vendor A= 456/1700, which is .268 or 27%
Vendor B= 607/1700, which is .357 or 36%
Vendor C= 637/1700, which is .374 or 37%
For a total of 100%
The top and bottom of the rectangle need to be equal and the two sides also need to be equal.
Set the equations to equal each other and solve for the letter.
Top and bottom:
3x-5 = x +1
Subtract 1x from each side:
2x -5 = 1
Add 5 to both sides:
2x = 6
Divide both sides by 2:
x = 6/2
X = 3
SIdes:
Now you know what X is replace x in the left side equation and solve:
2x-4 = 2(3) -4 = 6-4 = 2
The left side = 2, so the right side also needs to equal 2:
y-3 = 2
Add 3 to both sides:
y = 5
