An arithmetic sequence is a sequence in which each term after the first is equal to the sum of the preceding term and a constant, which is also known as the common difference of that arithmetic sequence. An increasing arithmetic sequence N consists of a set of distinct negative integers and an increasing arithmetic sequence P consists of a set of distinct positive integers. The sequence C contains all the terms of arithmetic sequences N and P such that the number of terms in sequence C is equal to the number of terms in arithmetic sequences N and P. Is sequence C an arithmetic sequence?
(1) The sum of the largest term of the sequence N and the smallest term of the sequence P is zero.
(2) For every integer in sequence N, there exists an integer in sequence P with the same magnitude.
  • 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 to answer the question asked.
  • d)
    EACH statement ALONE is sufficient to answer the question asked.

Steps 1 & 2: Understand Question and Draw Inferences
  • Increasing arithmetic sequence N consist of distinct negative integers with common difference n
  • Increasing arithmetic sequence P consist of distinct positive integers with common difference m.
  • Sequence C consist of terms of sequences N and P only.
To Find: Is sequence C an arithmetic sequence?
  • As sequence C consists of terms of arithmetic sequences N and P only, for sequence C to be arithmetic, sequences N and P should have the same common difference.
 
  • Also, sequences N and P will not have any common terms (as sequence N has all negative integers and sequence P has only positive integers), for sequence C to be arithmetic, the difference between the largest term of sequence N and the smallest term of sequence P should be equal to the common difference of the sequences.
 
  • For ex: Consider N = { -10, -9, -8……-1) and P = { 2, 3, 4, 5, ….}. In this case, both the sequences N and P have the same common difference but combining their terms does not result in an arithmetic sequence because the difference between -1 and 2 is not equal to the common difference of the sequences.
 
  • Consider N = { -14, -10, -6, -2} and P = {2, 6, 10}. In this case, as the difference between -2 and 2 is equal to the common differences of the sequences(i.e. 4), combining the terms of both the sequences results in an arithemetic sequence.
Step 3: Analyze Statement 1 independently
(1) The sum of the largest term of the sequence N and the smallest term of the sequence P is zero.
  • Let the largest term of sequence N be x and the smallest term of the sequence P be y.
  • So, x + y = 0
    • x = -y
    • So, difference between y and x = y – x = 2y
However we do not know the value of the common differences of the sequences as well as we do not know the value of y.
Insufficient to answer.
 
Step 4: Analyze Statement 2 independently
(2) For every integer in sequence N, there exists an integer in sequence P with the same magnitude.
  • It tells us that integers in sequence P consist of negative of all the integers in sequence N. Following cases are possible:
    • Number of terms of sequence N and P are the same. For ex: N= {-8, -6, -4} and P = {4, 6, 8}. In this case the common difference of both the sequences will be equal.
    • Number of terms in sequence P is greater than the number of terms in sequence N. For ex: N = {-8, -6, -4} and P = {3, 4, 5, 6, 7, 8, 9} or { 4, 6, 8, 10, 12}. In this case the common difference may or may not be equal.
 
Also, as we do not know the difference between the largest term of sequence N and the smallest term of sequence P, the statement is insufficient to answer.
 
Step 5: Analyze Both Statements Together (if needed)
  1. Difference between the largest term of sequence N( i.e. x) and the smallest term of sequence P(i.e. y) is equal to 2y.
  2. For every integer in sequence N, there exists an integer in sequence P with the same magnitude
Combining both the statements tell us that the largest term of sequence N (i.e. x) and the smallest term of sequence P(i.e. y ) have the same magnitude.
However it does not tell us:
  • the value of y and
  • if the sequences have the same common difference
Hence, combining the statements is also insufficient to answer.
