number sequence

[bremen]

[h=6]My nephew has this question for his math home work. He is in third grade and is working on addition and subtraction. We have all been at this for an hour.



Find the next two numbers in the sequence:

23,459
24,654
24,689

choices are:
23,568
23,678
24,789
24,809
22,345

1) There are infinitely many "correct" answers unless very specific instructinos are discussed.
2) Subtract successive values. This often leads to a clue.

23,459 - 24,654 = What?

24,654 - 24,689 = What?

Look at those two values and see if anything looks fun.

3) I know a man who answers ALL such questions with "-2"
