7. As shown in the figure, the beads on the bracelet are numbered from 1 to 22 in a counterclockwise direction starting from the pendant bead. Xiao Ming is playing a bead counting game, with the rule being: starting from bead 1, count natural numbers in a clockwise direction, but skip any number that contains the digit 7 or is a multiple of 7, and directly count the next number. For example: after counting to 6, the next number is 8; after counting to 13, the next number is 15, and so on. So, when counting to 100, which bead number $\qquad$ will it land on?
Parse: Skip multiples of 7, there are $[100 \div 7]=14$ multiples of 7 within 100; when counting to 100, 86 numbers should be counted $100-14=86,86 \div 22=3 \cdots 20$, when counting to 100, it should land on the 20th bead.
