we will learn how to fill in the missing numbers in given sequences.
e.g. Fill in the missing numbers in this sequence:
| A | B | 51 | 39 | 27 |
Answer:
Look for clues from neighbouring terms to work out the rule.
Here 51 – 39 and 39 – 27 both equal 12.
This means that the rule for the sequence is that each term goes down by 12.
B will be 51 + 12 = 63.
A will be 63 + 12 = 75.
So the final sequence is:
| 75 | 63 | 51 | 39 | 27 |
