Smallest 4-Digit Odd Number
The number 1001 is the smallest 4-digit odd number in the number system.
As 1000 is the smallest even four-digit number in the number system, we must determine the smallest odd four-digit number.
So, if we observe 1000 is an even number and 1000 – 1 = 999, which is a three-digit number. We need to see by adding 1 to 1000.
Here, 1000 + 1 = 1001, we can see that 1001 is a four-digit number, the smallest after 1000 as well as an odd number.
So, here we proved that 1001 is the smallest four-digit odd number.
