MCQ - 160-8892

Question:

The first term of sequence I is 10, and each term after the first term is 3 more than the preceding term. The first term of sequence II is 100, and each term after the first term is 3 less than the preceding term. If x is the 16th term of sequence I and y is the 16th term of sequence II, what is x + y ?

  1. 45
  2. 55
  3. 90
  4. 55

Correct Answer: D

Explanation:

Sequence I is an arithmetic sequence whose common difference is 3, and sequence II is an arithmetic sequence whose common difference is –3. For sequence I: a16 = 10 + 15(3) = 10 + 45 = 55 For sequence II: a16 = 100 + 15(–3) = 100 –45 = 55 So x = y = 55, and x + y = 110.
