Best answer 2 votes 2 votes The pattern is $+ 84, - 168, + 336,\dots$ i.e. $+ 84, - (84 * 2), + (84 * 4),\dots$ So, $815 - (84 * 8) = 815 - 672 = 143.$ papesh answered Aug 8, 2016 • edited Jun 24, 2022 by Anjana5051 papesh 246 points comment Share See all 0 reply Please log in or register to add a comment.
