Two patterns alternate here, with every third number following the alternate pattern.
In the first series 4, 7, 10,13, 16 ..... Starting with 4, +3 is added to each number to arrive at the next.
- $4+3=7$
- $7+3=10$
- $10+3=13$
- $13+3=16$
- $16+3=19$
In the second series 26, 20...Starting with 26, -6 is subtracted from each number to arrive at the next.
Therefore Next two number is 19(from 1st series), 14(from 2nd series). 19,14
So option (D) is correct.
