Very simple just see the table of 3.
3*2=6.
3*3=9.
3*4=12.
3*5=15.
3*6=18.
3*7=21.
3*8=24.
3*9=27.
3*10=30.
So 28 is not a multiple by 3. So wrong answer is 28.
3*2=6.
3*3=9.
3*4=12.
3*5=15.
3*6=18.
3*7=21.
3*8=24.
3*9=27.
3*10=30.
So 28 is not a multiple by 3. So wrong answer is 28.

3*2 = 6
3*3 = 9
3*4 = 12
3*5 = 15
3*6 = 18
3*7 = 21
3*8 = 24
3*9 = 27
3*10 = 30.
But 28 is not multiple of 3 so the answer is 28.
3*3 = 9
3*4 = 12
3*5 = 15
3*6 = 18
3*7 = 21
3*8 = 24
3*9 = 27
3*10 = 30.
But 28 is not multiple of 3 so the answer is 28.
