Answer:
D.
Step-by-step explanation:
There are two 3 numbered sequences.
21, 25, 18 and
29, 33, 18
The number 18 is common, and will be the third number
in the next series of 3 numbers.
Now the 7th number could be 8 higher than 29,
which is 37, or it could be 4 higher than 33, which
is also 37. Therefore the 7th number must be 37.
The 8th number must be 4 higher than 37, because
this is the difference between 25 and 21 and also
the difference between 33 and 29.
So we can contiune indefinetly,
21, 25, 18,
29, 33, 18,
37, 41, 18,
45, 49, 18,
53, 57, 18 ...
and so on.
