The sequence formed by using the numbers is termed as the number series.So in this question from day one to day seven each day the sold items are multiplied by 4.

So the mathematical expression will be given as:

$=(12\times 4^0)+(12\times 4^1)+(12\times 4^2)+(12\times 4^3)+(12\times 4^4)+(12\times 4^5)+(12\times 4^6)$

$=12+48+192+768+3072+12288+49152\\\\=65532$

Hence the total number of the bags sold by the shopkeeper will be 65532.
