Freddie the frog loves jumping around on number lines. He always likes to make a clever number sequence. Use your finger to follow the jumps that he makes.
Example
Count the frog's jumps to work out missing numbers in the sequence.
Pop your finger on the first number, then follow the jumps. Are the numbers getting bigger or smaller? Is Freddie going backwards or forwards? Can you see a pattern? What could the missing number be? What could the next number be?
10 | 20 | 30 | a | b |
Answer
Look at the pattern of the sequence.
Freddie is jumping forwards 10 places at a time: 10, 20, 30 etc.
To find our missing numbers, we need to to count forwards ten (or add 10) to the previous number.
30 + 10 = 40
40 + 10 = 50
So we can see that:
a = 40
b = 50
How do you feel about jumping forwards?
