House numbers on Mathematics Street follow a pattern.
Green blocks are empty spaces where no houses are built.
What are the house numbers of red and yellow blocks?
What is the reason behind empty spaces (green blocks) on the street?

First:
Create a sequence with the values of the first row and the reversed order of the second, so
r, 3415, 4392, ..., 3326, 4543, g, g, g, ..., y
Then
The last two digits of each value are the
nth digit of PI:r,r,1,5,9,2,6,5,3,5,...,1,9,y,y. The missing values arer=..14andy=..71
And
Each of the first two digits of every value are the number of letters in the words formed by the digital recitation of Pi in the English language.:
r,r,3,4,4,3,...(one, five, nine, two, ...). The missing values arer=34..andy=53..
Red and Yellow:
Are therefore
r = 3414andy = 5371
The Greens:
Are invalid because
5538, 5332, 5479are repetitions, and therefore would not constitute valid house numbers on the same street.

$\begingroup$ @chandanr777 Should be correct now, counting is hard :) $\endgroup$ Oct 7, 2022 at 10:52

$\begingroup$ Haha. Yes. It's correct now. From my experience, good logicians usually make silly counting errors :) $\endgroup$ Oct 7, 2022 at 11:04
