Detailed explanation-1: -Hence, 17, 32, 19, 29, 21, 26, 23, 25, 23 will be the correct sequence or next term of numbers in the series.
Detailed explanation-2: -Prime no between 1 to 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
Detailed explanation-3: -The primes up to 50 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43 and 47. The sequence of gaps-the differences between each prime and the next-is 1, 2, 2, 4, 2, 4, 2, 4, 6, 2, 6, 4, 2 and 4. The number 1 appears only once because all primes except for 2 are odd. The rest of the gaps are even numbers.
Detailed explanation-4: -Which one of the following numbers belong to the given series 18, 26, 34, 42 and 50? a)436b)58c)232d)132Correct answer is option ‘B’.
Detailed explanation-5: -Detailed Solution This is a simple alternating addition and subtraction series. In the first pattern, 3 is added; In the second pattern, 2 is subtracted. Hence, the correct answer is “10".
