B. 2/9
C. 9/2
D. 9/4
E. 1
Correct Answer: A
Explanation/Reference:
Explanation:
The denominator of each term in the pattern is equal to 2 raised to the power given in the numerator. The numerator decreases by 1 from one term to the next. Since 10 is the numerator of the first term, 10 – 9, or 1, will be the numerator of the tenth term. 21 = 2, so the tenth term will be 1/2.
