(21+ 4), 18 = 25, 18.
(25+ 4), 18 = 29, 18.
(29+ 4), 18 = 33, 18.
(33+ 4), 18 = 37, 18.

So the answer should be 37, 18.

For every number, 4 is added and 18 takes the third place.

Therefore, the answer is 37 41.

The correct answer is 37, 18. But they say it is 37, 41. Why so? please explain.

"(21) (21+4) 18 (25+4) (29+4) 18 (33+4) (37+4) 18 " where they gave up to 2 and 18. So in b/w 2nd and 3rd 18 two numbers are there. So after 37 & 41 will be the repeated number 18.

The difference between two numbers before 18 is 4, 18 appears on 3, 6, 9 positions, then the answer is 37, 41.

Add 8 to 21 and 25, You get 29 33.
Add 8 to 29 and 33, You get 37 41.
And so on.

(29+4), 18 = 33,18
(33+4),18 = 37,18

So the answer is 37, 18.

21+4=25
25+4=29
29+4=33
33+4=37
And 3rd no is same.
So 37+4=41 this is the answer.
