Worked practice questions

As per your syllabus, Math, what is a SEQUENCE?

  1. An ordered list of numbers (or objects) where each number is a TERM of the sequence
  2. An unordered set of numbers
  3. A geometric shape
  4. A single number
Show answer and solution

Correct answer: A. An ordered list of numbers (or objects) where each number is a TERM of the sequence

As per your syllabus, a sequence = ordered list of numbers, each called a term. The other options misstate.

As per your syllabus, the sequence 1, 3, 6, 10, 15, 21,... is called what?

  1. Prime numbers
  2. Square numbers
  3. Triangular numbers (each term is the sum of natural numbers up to that position)
  4. Odd numbers
Show answer and solution

Correct answer: C. Triangular numbers (each term is the sum of natural numbers up to that position)

As per your syllabus, 1, 3, 6, 10, 15, 21 are triangular numbers (1 = 1, 3 = 1+2, 6 = 1+2+3,...).

As per your syllabus, the sequence 1, 4, 9, 16, 25, 36,... consists of which numbers?

  1. Triangular numbers
  2. Cube numbers
  3. Fibonacci numbers
  4. Square numbers (n² for n = 1, 2, 3, ...)
Show answer and solution

Correct answer: D. Square numbers (n² for n = 1, 2, 3, ...)

As per your syllabus, 1, 4, 9, 16, 25, 36 are squares of natural numbers (n²). The other options misclassify.
