 OFFSET 1,1 COMMENTS The numerator of the corresponding smallest ratio is the largest numerator on the n-th row of A341053, hence, a(n) is the last term of the n-th 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. LINKS Table of n, a(n) for n=1..70. FORMULA a(n) = A350254(n) iff A341052(n) = 1. EXAMPLE There exist A341051(9) = 11 integers in the largest possible string with 9-digit 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. CROSSREFS Cf. A341051, A341052, A341053, A350254.
