Which pattern do you see in the multiples of 9? and Which pattern do you see in the multiples of 1?
9, 18, 27, 36, 45, 54, 63, 72, 81..
The tens column keeps getting bigger by one and the ones column keeps getting smaller by 1. Do you mean multiples of 11 for the second question?
In order to identify patterns in numbers, let's first look at the multiples of 9 and the multiples of 1 separately.
Multiples of 9:
To find the multiples of 9, we can simply multiply 9 by any whole number.
0 x 9 = 0
1 x 9 = 9
2 x 9 = 18
3 x 9 = 27
4 x 9 = 36
5 x 9 = 45
...
From this pattern, we can observe that the multiples of 9 always end in either 0 or 9. Moreover, the digit sums of these multiples also follow a pattern. The sum of the digits in the multiples of 9 is also always divisible by 9. For example, the digit sums of 9, 18, 27, 36, etc. are all equal to 9, which is divisible by 9.
Multiples of 1:
For multiples of 1, we can multiply 1 by any whole number. However, in this case, the multiples of 1 will always be the same as the whole numbers themselves.
0 x 1 = 0
1 x 1 = 1
2 x 1 = 2
3 x 1 = 3
4 x 1 = 4
5 x 1 = 5
...
As we can see, the multiples of 1 are simply the counting numbers in order. There is no specific pattern other than the fact that each multiple of 1 is equal to the corresponding whole number.
In summary, the pattern in the multiples of 9 is that they always end in 0 or 9, and their digit sums are always divisible by 9. On the other hand, the multiples of 1 are simply the counting numbers themselves.
