Assertion and reason

Read exercise and reference answers
Questions
  1. Reason
    Constant differences are the commoner pattern and are quicker to spot.
    Verdict
    Both are true; the reason explains the assertion.
    Assertion
    Checking differences before ratios saves time on a series item.
  2. Reason
    It is defined as an arrangement in definite order according to a rule.
    Verdict
    Both are true; the reason explains the assertion.
    Assertion
    A sequence must follow some rule.
  3. Reason
    A sequence arranges numbers in a definite order.
    Verdict
    The assertion is false and the reason is true.
    Assertion
    A series is just another name for a sequence.
The reason must genuinely explain the assertion. Source: syllabus Maths, Ch 9 Sequences and Series.

Questions
  1. False statement
    A GP has a constant difference
    Statements
    1. A GP has a constant ratio
    2. A sequence has a definite order
    3. A GP has a constant difference
  2. False statement
    A series is an ordered list
    Statements
    1. A series is an ordered list
    2. A series is the sum of a sequence's terms
    3. A sequence is an ordered list
  3. False statement
    2, 6, 18 has difference 4
    Statements
    1. 2, 6, 18 has ratio 3
    2. 2, 6, 18 has difference 4
    3. 3, 7, 11 has difference 4
The false line swaps difference for ratio, or sequence for series. Source: syllabus Maths, Ch 9 Sequences and Series.

Questions
  1. Question
    Three of these statements about a GP are false.
    Choices
    1. Item
      Consecutive terms share a constant ratio
      Correct
      Yes
    2. Explanation
      That describes an arithmetic progression.
      Item
      Consecutive terms share a difference
    3. Explanation
      A ratio below one makes the terms shrink.
      Item
      Its terms must always increase
    4. Explanation
      The nth term multiplies, it does not add.
      Item
      Its nth term is a plus n times r
Each trap confuses the two kinds of progression. Source: syllabus Maths, Ch 9 Sequences and Series.
