Question

Look at this series: XXIV, XX, __, XII, VIII, ... What number should fill the blank?

Answer 1

In the first blank it will be XVI and in the last blank IV because 4 is subtracted from each Roman number

Answer 2

XXIV,XX, XVI , XII , VIII
24  ,  20 ,  16  ,  12  ,  8

WE SUBTRACT 4 FROM EACH 
24-4 = 20 - 4 = 16 - 4 = 12 - 4 = 8 

THANK YOU HOPE THIS WILL HELP YOU
