Answer 2

Answer:

137

Step-by-step explanation:

here they have given to find out the odd number , the number which does not belong to the group.

Let us try by multiplying the given numbers by 3. So

5 x 3 = 15

15 x 3 = 45

45 x 3 = 135

137 x 3 = 411

411 x 3 =1233

We can see the odd number is 137, Because 45 when multiplied by 3 we get 135 and not 137.
