P.S......

If you want the comparison value to be variable, instead of hardcoding it
into the formula use a cell to hold that variable and then just refer to
that cell.

When I filter this set of data, the function can locate
5 and 9 but can not locate 5409 and 5413.

It works for me. See this screencap:

I suspect you didn't modify the formula correctly for the different data
set.

Hi,

Thanks for the input, I used your way to filter my data, but instead of
3, I
filtered for 4. The function you provided works well on small number but
does
not work on big numbers. For example
5 9
3018 1423
4107 5025
4306 5413
5409 13199
15027 19841
18823 25813
23404 25948
27633 26083
42219
42343
42829


When I filter this set of data, the function can locate 5 and 9 but can
not
locate 5409 and 5413.
All my numbers are whole number and none negative. number in both A and B
are both listed from smallest to biggest. Total Entry of A can be
smaller,
bigger or equal to B.
Is there a way I can solve this problem?

This seems to do what you want:

Enter this formula in D1 as an array using the key combination of
CTRL,SHIFT,ENTER (not just ENTER):

=IF(ISERROR(SMALL(IF(ISNUMBER(MATCH(A$1:A$4+3,B$1: B$4,0)),ROW(A$1:A$4)-MIN(ROW(A$1:A$4))+1),ROWS($1:1))),"",INDEX(A$1:A$4 ,SMALL(IF(ISNUMBER(MATCH(A$1:A$4+3,B$1:B$4,0)),ROW (A$1:A$4)-MIN(ROW(A$1:A$4))+1),ROWS($1:1))))

Enter this formula in E1:

=IF(D1="","",D1+3)

Select both D1 and E1 and copy down until you get blanks.

Hi,

I have two column of number, A and B. I would like to find all the
possibility for (# in B)- (#in A) is equal to 3 then return the
corresponding
numbers.

e.g

A B
1 3
2 4
5 8
7 13

4-1=3, return 1 & 4
8-5=5, return 5 & 8

Any input would be helpful
Jason
