      Question

      A series given below has a missing term (Z), find the

      value of Z. 3, 10, 36, (Z), 770, 4632 If Z is the first term of another sequence and next term is formed by adding consecutive prime numbers starting from 7, find the fifth term of the sequence.
      A 200 Correct Answer Incorrect Answer
      B 238 Correct Answer Incorrect Answer
      C 282 Correct Answer Incorrect Answer
      D 250 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      ATQ, 3 ├Ч 2 + 4 = 10 10 ├Ч 3 + 6 = 36 36 ├Ч 4 + 8 = 144 + 8 = 152 152 ├Ч 5 + 10 = 760 + 10 = 770 770 ├Ч 6 + 12 = 4620 + 12 = 4632 Value of Z = 152 Now, second sequence starting with Z and adding consecutive primes from 7: 152 + 7 = 159 159 + 11 = 170 170 + 13 = 183 183 + 17 = 200 So, the 5th term of the new sequence = 200
