1,1

Table of n, a(n) for n=1..67.

n = 3: A116151(4) - A116151(3) = 173 - 23 = 150, product of first 3 primes is 2*3*5 = 30. Hence a(3) = 150 / 30 = 5.

Cf. A116151, A002110 (product of first n primes).

Sequence in context: A003432 A179332 A081938 * A250745 A109204 A250747

Adjacent sequences: A129497 A129498 A129499 * A129501 A129502 A129503
