hi buddy!!!!!

its fine....u got d correct answer..c my solution..



Let pn be the prob of return after distance n. Then pn+1 = (1-pn)/3, because to return after n+1, it must have been at a different vertex after n, and then chosen the correct edge to return. Obv p1 = 0, so p2 = 1/3, p3 = 2/9, p4 = 7/27, p5 = 20/81, p6 = 61/243, p7 = 182/729
