What are the multiples of 20?

Answer 1

the multiples of 20 are 20,40,60,80,100,120,140,160,180,200,220,240,260,280,300,320,340,360,380,400,420,440,460,480,500 and so on. Just keep adding 20!
20, 40, 60 and so on.
The multiples start with 20. And then 20 is added to every preceding number.

For example, 1x20=20.

The next multiple would by 20+20= 40. Similarly, the next would 40+20 (Adding 20 to the preceding number- the preceding number would be the second multiple in this case).

Thus the multiples will be 20,40,60,80,100,120 and so on. You can't determine all the multiples as the greatest number is unknown.
