I have a problem that is stumping me. In cells A1 through A10, I have numbers 1-10. In cells B1-B10 I have corresponding identifiers, Apples, Oranges, Pears. It looks like this

A B

1 Apples
2 Apples
3 Oranges
4 Oranges
5 Apples
6 Pears
7 Oranges
8 Pears
9 Oranges
10 Apples

I need a formula that I can copy down that looks in column B for "Oranges" and returns the corresponding number that is next largest above the number it already found. The result would look like below...

3
4
7
9

Any feedback would be most helpful. Thank you
