What is the value of the sum of a sequence of x consecutive even integers?
(1) x = 5
(2) The least integer in the sequence is 6
  • a)
    Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked
  • b)
    Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked
  • c)
    BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient
  • d)
    EACH statement ALONE is sufficient to answer the question asked
  • e)
    Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed

Statement 1: x = 5
We don't know where the sequence starts. For example:
Case a: the 5 numbers are {2, 4, 6, 8, 10}, in which case the sum = 30
Case b: the 5 numbers are {4, 6, 8, 10, 12}, in which case the sum = 40
Since we cannot answer the target question with certainty, statement 1 is NOT SUFFICIENT
Statement 2: The least integer in the sequence is 6
We don't know how many integers are in the sequence. For example:
Case a: the numbers are {6, 8}, in which case the sum = 14
Case b: the numbers are {6, 8, 10}, in which case the sum = 24
Since we cannot answer the target question with certainty, statement 2 is NOT SUFFICIENT
Statements 1 and 2 combined
We now know that the numbers are {6, 8, 10, 12, 14}, in which case the sum = 50
Since we can answer the target question with certainty, the combined statements are SUFFICIENT
