If the pattern starts with five marbles on the first line and each consecutive line has one more marble than the previous line, the number of marbles on each line would be as follows: 5 (first line), 6 (second line), 7 (third line), 8 (fourth line), 9 (fifth line), 10 (sixth line), and 11 (seventh line). Therefore, the seventh line will have 11 marbles.
