Q32: If x is a positive integer, is the remainder 0 when (3^x + 1)/10?
(1) x = 3n + 2, where n is a positive integer.
(2) x > 4
whenever i take too quick decision, i fall on the trap. therefore i slipped on this one. i thought x = 3n + 2 has a pattern but when x = 4n + 2, then only it would have a pattern.
agree with you guys.
thanks for good job.
