In following questions, one term in number series is incorrect. - Find out the incorrect number
10, 14, 28, 32, 64, 68, 132
Answer: D. 132
Alternately, the numbers are increased by four and doubled to get the next number>
Thus, 10 + 4 = 14;
14 * 2 = 28;
28 + 4 = 32;
32 * 2 =64 and so on.
So, 132 is wrong and must be replaced by (68 * 2) i.e. 136.
