1115 06421041aed76c064b84be74c6421041aed76c064b84be74cWhich number from the options will replace the question mark (?) in the following series?
3, 13, 53, 213, ?
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.
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.
What comes next in the series?
765, 642, 519, 396, 273 ?
