Missing alphanumeric number in the sequence
 
Try the below formula ..

'to check for sequence AA01 to AA05
=IF(SUMPRODUCT(--ISNA(MATCH("AA"&TEXT(ROW(A1:A5),"00"),A:A,0))),"Nu mbers
missing","No numbers missing")


'to check for sequence AA01 to AA10
=IF(SUMPRODUCT(--ISNA(MATCH("AA"&TEXT(ROW(A1:A10),"00"),A:A,0))),"N umbers
missing","No numbers missing")
