Your supposed to look for the next five numbers and to do that you add them with odd numbers For instance: 1 to 4 is 3. 3+1=4 4 to 9 is 5. 5+4=9.
An easier way to do it is subtract the number with the before number For instance: 9-4=5 then add 4 & 5 and you get 9. 16-9=7 and then add 7 to 9 which is 16. Do you get it? Hope I wasn’t giving away the answers. If you don’t get it, message me.
