What is the nth term of the sequence 3⁄2, 5⁄3, 7⁄4, 9⁄5, …?

Answer and explanation

Correct answer: (2n + 1)⁄(n + 1)

The governing concept is finding a general rule for a sequence of fractions by examining the numerator and denominator separately. The numerators are 3, 5, 7, and 9. Starting with n = 1, this pattern is 2n + 1. The denominators are 2, 3, 4, and 5, which follow the rule n + 1. Combining the two independent patterns gives aₙ = (2n + 1)⁄(n + 1), so option A is correct. Verification is immediate: n = 1 gives 3⁄2, n = 2 gives 5⁄3, and n = 4 gives 9⁄5. Option B begins with 1⁄2, option C reverses the roles and structure of the expressions, and option D gives 3 when n = 1 rather than 3⁄2.
