I am a four digit number. I have a 1 in my thousands place. The digit in my ones place is 6 more than the thousands. The digit is my tens place is my thousand plus ones. The missing digit is largest single digit odd numbers.

The four digit number is 1,927

Step-by-step explanation:

Let the four digits number be ABCD

now let's test the information given.

There is 1 in the thousand place, this means A is 1

The ones digit i. e D is 6 more than the thousands. This means D is 6 + 1 = 7

Digit in tens place is thousand plus 1. The tens digit here is C. The value is 1 + 1 which is 2

And lastly the missing digit which is the hundred digit is largest single digit odd number and that is 9

The four digit number is thus 1927
