COMMENTS

The numerator of the corresponding smallest ratio is the largest numerator on the nth row of A341053, hence, a(n) is the last term of the nth row of A341053.
The denominator of these corresponding ratios is equal to a(n)  1.
This sequence is not increasing as a(38) = 16 > a(39) = 15.

FORMULA



EXAMPLE

There exist A341051(9) = 11 integers in the largest possible string with 9digit numbers that are in geometric progression, and three such strings are obtained with the A341052(9) = 3 distinct following ratios 5/4 > 6/5 > 7/6. The smallest ratio is 7/6 and a(9) = 7.
