Paragraph: The product of 5 consecutive terms of an AP is 229635 . The first, second and fifth terms are in GP. Question: What is the sum of all five terms?

Options

  1. A60
  2. B65
  3. C75
  4. D80

Correct answer

C. 75

Step-by-step solution

Using the value of d in equation (ii), we have, 5 6=2 a a=15 The required terms of A.P. are 3,9,15,21,27 . So, required sum =3+9+15+21+27=75 .
