What is an ordered list of items, usually numbers, called?

  1. A sequence
  2. A function
  3. A gradient
  4. A variable
Show answer and solution

Correct answer: A. A sequence

1. Patterns in numbers are written down as an ordered list. 2. A sequence is an ordered list of items, usually numbers. 3. Each separate item that makes up the list is called a term. _Source: Siyavula Mathematics Grade 10 (Everything Maths, CC BY 4.0), Chapter 3: Number patterns_

In a linear sequence, what exactly is the common difference?

  1. Each term times the one before
  2. Each term minus the one before
  3. Each term plus the one before
  4. The first term of the whole list
Show answer and solution

Correct answer: B. Each term minus the one before

1. A linear sequence grows or shrinks by the same step every time. 2. The common difference is the difference between any term and the term before it. 3. Subtracting in the wrong order gives the answer the wrong sign. 4. If that difference is not the same for every pair, the sequence is not linear. _Source: Siyavula Mathematics Grade 10 (Everything Maths, CC BY 4.0), Chapter 3: Number patterns_

What name is given to sequences that have a common difference?

  1. Square sequences
  2. Random sequences
  3. Linear sequences
  4. Cubic sequences
Show answer and solution

Correct answer: C. Linear sequences

1. Some sequences grow by a fixed step and others do not. 2. Sequences with a common difference are called linear sequences. 3. Their general formula is built from the common difference and a constant. 4. That common difference always turns out to be the coefficient of the position number. _Source: Siyavula Mathematics Grade 10 (Everything Maths, CC BY 4.0), Chapter 3: Number patterns_
