While trying (unsuccessfully) to solve your puzzle I discovered multiple sequences beginning 1,2,4,8,16,77.
I thought the next term was supposed to be 145,668 with the comma separating thousands (rather than two terms 145 and 668) and even found such a sequence 1,2,4,8,16,77,145668 but the next term wasn’t 1345. Maybe I should post those sequences as puzzles here.
