Directions: The following problem has a question and two statements labelled (1) and (2). You have to decide whether the statements are sufficient to answer the question. Mark your answer as

A sequence of numbers is given by the rule a_n = a_n–1 + 2. Is a₁₀ an even integer? (1) a₁ is even. (2) a₉ is 24.

if you can get the answer from (1) alone, but not from (2) alone

if you can get the answer from (2) alone, but not from (1) alone

if you can get the answer from (1) and (2) together, although neither statement by itself suffices

if (1) alone suffices and (2) alone suffices

if you cannot get the answer from (1) and (2) together, and need even more data
