Question

• Add the numbers in the same position of the first two
patterns. Why do we get only multiple of 10? Do we
get all multiples of 10 like this?
​

Answer 1

Answer:

Multiples of 10 are the products when an integer is multiplied by 10. Did you know that 10 is the sum of the first four consecutive whole numbers, that is, Then we multiply 10 by 3 to get the third multiple of 10 which is 30, and so on.  Out of the numbers listed above only 40 is lying between 0 and 50 which ends with 0.
