Order of 3 numbers in a non ordered range

I need some help.

I have to find the order which 3 numbers (C2, C3 and C4) occurs in a non ordered range.

See attached file.

The question is that the match is not exact, it varies from -2 to +2 over C2, C3 and C4, like:
AND(>(C2-2);<(C2+2)).

In E2 I need to know the first number that appears on the range A2:A15, then in E3 the second and in E4 the third.

The formula that make some sense (even if they don't work):
=INDEX(A2:A15,MATCH(C2,AND(A2:A15>C3-2,A2:A15<C3+2),0),1)
=INDIRECT("A"&MATCH(AND(>C2-2,<C2+2),A2:A15,0))

Please, I'm really dazed!

hi there. i tried to create a formula without helper columns, but i just couldn't think of any. my solution is to create an array formula in F2:
=MATCH(1,($A$2:$A$15>=C2-2)*($A$2:$A$15<=C2+2),0)
...confirmed by pressing CTRL+SHIFT+ENTER to activate the array, not just ENTER. You will know the array is active when you see curly braces { } appear around your formula. If you do not CTRL+SHIFT+ENTER you will get an error or a clearly incorrect answer. Press F2 on that cell and try again. copy down to F4

then in E2:
=INDEX($C$2:$C$4,MATCH(SMALL($F$2:$F$4,ROWS(E$2:E2)),$F$2:$F$4,0))

hope you get a better answer without the helper columns.

interesting..but what happens with say 5 in cell a7 it meets both 3 and 7 requirements
