10, 26, 74, 218, 654, 1946, 5834

Question: 10, 26, 74, 218, 654, 1946, 5834

[A].

26

[B].

74

[C].

218

[D].

654

Answer: Option D

Explanation:

2nd term = (1st term) x 3 – 4 = 10 x 3 – 4 = 26.

3rd term = (2nd term) x 3 – 4 = 26 x 3 – 4 = 74.

4th term = (3th term) x 3 – 4 = 74 x 3 – 4 = 218.

5th term = (4th term) x 3 – 4 = 218 x 3 – 4 = 650.

5th term must be 650 instead of 654.
