These numbers belong together in a group. 25 ,40 ,110, 55.
These numbers do not belong in the group. 33, 71 ,4 ,106
Which number belong in the group?
75,205, 87, 43
The answer is 205. If you add 15 every time you end up with the numbers. 25+15=40. 40+15=55. If you continue the pattern the next numbers will be 70 so 75 will never be an answer so you can eliminate that answer. 87 and 43 are do not end in 0 or 5 so you know its not those two. So the answer would have to be 205. To check to see if it is correct you can add 15 on till you get to 205. I hope this helps ;)
