In Column A, I have numbers from 1 to 40.

From cell B16 and so on, I want to display a series of 9 continuous numbers which did not appear in last 15 rows(range A1:A15)

COLUMN A

24
40
35
30
33
2
25
17
8
0
20
39
30

DISPLAY "NONE" as no continuous 9 numbers were missing in the last 15 rows


1
12
24
40
35
30
33
2

DISPLAY "3-11" as continuous 9 numbers from 3 to 11 were missing in the last 15 rows

Is this possible?

Please advice.

Array formula in B16
=MAX(FREQUENCY(IF(ISNA(MATCH(ROW($1:$41)-1,A2:A16,0)),ROW($1:$41)-1),A2:A16))
Ctrl+Shift+Enter

Array formula in C16
=IF(B16>=9,INDEX(A2:A16,MATCH(B16,FREQUENCY(IF(ISNA(MATCH(ROW($1:$41)-1,A2:A16,0)),ROW($1:$41)-1),A2:A16),0))-1,"N/A")
Ctrl+Shift+Enter

Regular formula in E16 copied across as long as needed (till N16 for example)
=IF($B16>=9,IF($B16>=COLUMNS($E16:E16),$C16-$B16+COLUMNS($E2:E2),""),"")
confirmed with just Enter

Then
select cells B15:N16 and copy (Ctrl+C)
select cell B30 and paste (Ctrl+V)

Done!

Hope this helps

oops... the formula in E16 has a typo (not important for calculation)

New version
=IF($B16>=9,IF($B16>=COLUMNS($E16:E16),$C16-$B16+COLUMNS($E16:E16),""),"")
