  • KEY STAGE 2 NUMBER SEQUENCESA sequence is usually a list of numbers in a pattern.Look at the difference between each number to spot the rule for the pattern.

    1. Write the missing numbers in thesesequences.What is the rule for each of them?

    2. Negativenumbers go back past zero. Writethe missing numbers on these number lines.

    1. Use the numbers from the grid to answer these questions.

    a Which two numbers total 140?

    b What is the sum of the two largest numbers?

    c What is the total of the three smallest numbers?

    d What is the sum of the four corner numbers?

    e Which two numbers add up to 210?

    f What is the sum of the numbers in the top row?

    2. Use a written method to solve these sums.
