<h3>
Answer: Choice C) 11 + 13 + 15 + 17 + ...</h3>
=====================================================
Explanation:
We're adding terms in the form (2n+5)
The first term is when n = 3, so
2n+5 = 2*3+5 = 6+5 = 11
The next term is when n = 4, so
2n+5 = 2*4+5 = 8+5 = 13
The next term is when n = 5, so
2n+5 = 2*5+5 = 10+5 = 15
And so on
This means,

which matches with choice C. The three dots indicates the pattern goes on forever.
-------------------
Choice B does not have these dots, so that's why choice B is not the answer. If we replaced the infinity symbol with 7, then choice B would be the answer.
I.e,

The answer is 438.6...
(528+1/5)-(89+3/5)=438.6
Solve for x:
-59 = 7 x
-59 = 7 x is equivalent to 7 x = -59:
7 x = -59
Divide both sides of 7 x = -59 by 7:
(7 x)/7 = (-59)/7
7/7 = 1:
Answer: x = (-59)/7
2500 kilobytes/ 5 minutes= 500 kilobytes per minute
Final answer: 500 kilobytes per minute
