Worked practice questions

A list of numbers in which each term comes from adding a fixed number to the one before it is called:

  1. An arithmetic progression
  2. A geometric progression
  3. A harmonic progression
  4. A quadratic progression
Show answer and solution

Correct answer: A. An arithmetic progression

1. The first term is the starting point. 2. Every later term adds the same fixed number. 3. That list is an arithmetic progression. _Source: syllabus Mathematics, Chapter 5, Arithmetic Progressions._

The fixed number added each time in such a list is called the:

  1. Common fraction
  2. Common difference
  3. Common divisor
  4. Common multiple
Show answer and solution

Correct answer: B. Common difference

1. It is the same at every step. 2. It may be positive, negative or zero. 3. It is the common difference. _Source: syllabus Mathematics, Chapter 5, Arithmetic Progressions._

Shakila's money box holds 100, 150, 200, 250 rupees on successive birthdays. The common difference is:

  1. 50
  2. 40
  3. 60
  4. 25
Show answer and solution

Correct answer: A. 50

1. Subtract each term from the next. 2. 150 minus 100 is 50, and so on. 3. The common difference is 50. _Source: syllabus Mathematics, Chapter 5, Arithmetic Progressions._
