 OFFSET 1,1 LINKS Zak Seidov, Table of n, a(n) for n = 1..10000 FORMULA a(n) = A046308(n+1) - A046308(n). EXAMPLE a(1) = 64 = 192-128 where 128 is the first 7-almost prime and 192 is the second. a(2) = 96 = 288-192. a(3) = 32 = 320-288. a(4) = 112 = 432-320. a(5) = 16 = 448-432. a(6) = 32 = 480-448. a(7) = 168 = 648-480. a(8) = 24 = 672-648.
