which choice has a value that is closest to the value of the following expression?
A.1/4 C.1/6
B.1/5 D.1/7
The value of the expression cannot be determined without knowing the value of x. The expression has the form of a geometric series with first term 1 and common ratio x/2. Therefore, its value is:
1 + (x/2) + (x/2)^2 + (x/2)^3 + ... = 1/(1 - x/2)
Without knowing x, we cannot simplify the expression further or determine which choice is closest in value.
