Worked practice questions

In a geometric progression, the constant multiplier is called the common:

  1. Result
  2. Ratio
  3. Reason
  4. Region
Show answer and solution

Correct answer: B. Ratio

1. Each term is obtained by multiplying the previous one. 2. That multiplier is constant throughout. 3. Here a is called the first term and r is called the common ratio of the GP. 4. So the answer is the ratio. _Source: syllabus Mathematics, Ch 8 'Sequences and Series'_

The number at the nth position of a sequence is called the:

  1. nth tier
  2. nth trait
  3. nth term
  4. nth turn
Show answer and solution

Correct answer: C. nth term

1. Positions in a sequence are numbered. 2. The entry at a given position takes that number. 3. The nth term is the number at the nth position of the sequence. 4. So the answer is the nth term. _Source: syllabus Mathematics, Ch 8 'Sequences and Series'_

A sequence that never ends is called an:

  1. Inverted sequence
  2. Indexed sequence
  3. Interior sequence
  4. Infinite sequence
Show answer and solution

Correct answer: D. Infinite sequence

1. Some sequences have a last term and some do not. 2. The one without a last term runs on forever. 3. The sequence of successive quotients is an infinite sequence, infinite in the sense that it never ends. 4. So the answer is an infinite sequence. _Source: syllabus Mathematics, Ch 8 'Sequences and Series'_
