Question 1208684
<font color=black size=3>
I have edited out the dollar signs from your question. 
It seems to be a strange copy/paste error.


The number 1,000,002 is the smallest 7-digit number where its digits add to 3.
As such, that large number is a multiple of 3.


Then 1,000,002+3 = 1,000,005 is the next multiple of 3 and 1,000,005+3 = 1,000,008 is the next, and so on.
This arithmetic sequence has common difference d = 3.


The nth term of this arithmetic sequence is 
a<sub>n</sub> = 1,000,002 + 3(n-1)


The largest 7-digit multiple of 3 is 9,999,999. 
We don't have to add up the digits since 9 is a multiple of 3, sums of 9 will also get us a multiple of 3.


If you solved this equation
9,999,999 = 1,000,002 + 3(n-1)
then you would get the result n = 3,000,000 = 3 million
I'll let the student handle the scratch work.



Answer: 3,000,000 aka 3 million
