1113122110 In given series 2nd number gives number of  which digits present in the 1st number and so on continues for 3rd ,4th,... Here 1st no. has only one zero, so  2nd no. is 10 and 2nd no. has one 1 and one 0,so 3rd no. is 1110, so like that 5th no. has one 1,one 3,one 2,two 1's and one 0.So the next no. is 1113122110.

Answer: A) 12 Explanation: The given series follows a pattern that,   4 + 32 = 4 + 9 = 1313 + 52 = 13 + 25 = 3838 + 72 = 38 + 49 = 8787 + 92 = 87 + 81 = 198    Hence, the odd man in the given number series is 12.

Answer: A) 98 Explanation: The given number series is  3, 5, 8, 15, 28, 51, ? Here the pattern it follows is 3 3 + 2 = 5 ( add prime number less than 3 i.e, 2) 5 + 3 = 8 (3 is prime number less than 5) 8 + 7 = 15 (7 is prime number less than 8) 15 + 13 = 28 (13 is prime number less than 15) 28 + 23 = 51 (23 is prime number less than 28) 51 + 47 = 98 (47 is prime number less than 51)   Hence, the next number in the given number series is 98.
