3) 55,135,165
4) 35,63,78

Answer 1

1) 9,36,81 I think it's help you
first one is divided 9 or 3 and this 9-3= 6 different of number.
second one is divided 2,4,6,8 and 4-2=2, 6-4=2, 8-6=2 different of number.
third one is divided 5,3 and this different of number 5-3=2
fourth one is divided also 5,3 and these numbers different is 5-3=2
then options 2,3,4, different of number is only one number that is 2.which is different of number ? that option 1. because it's different of number is 6 so first one is odd number

2:88 because it's not divisible by 16
3:55 because it is not divisible by 3
