Question

Find out the wrong number in the series:. 4, 5 ,15 ,49, 201 ,1011 ,6073​

Answer 1

Answer:

5

Step-by-step explanation:

2nd term = (1st term × 1 + 2) = (4 × 1 + 2) = 6;

3rd term = (2nd term × 2 + 3) = (6 × 2 + 3) = 15;

4th term = (3rd term × 3 + 4) = (15 × 3 + 4) = 49;

5th term = (4th term × 4 + 5) = (49 × 4 + 5) = 210; and so on.

Therefore 5 is wrong.
