(In reply to re(3): questions, possible solution to 2 digit multiplicand by brianjn)

If I understand the conditions correctly, the answer may be possibly:

64 = 64 × 1
68 = 34 × 2
72 = 24 × 3
76 = 19 × 4
80 = 16 × 5
84 = 14 × 6  (or, for #1, 12 × 7)

I did not work through all the possibilities. Without programming software the work is tedious. Two other product sequences of six terms are {65, 70, 75, 80, 85, 90} and {96, 102, 108, 114, 120, 126}.
