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

37, 18 is the correct answer.
21 + 4 = 25.
25 + 4 = 29.
29 + 4 = 33.
33 + 4 = 37.
21 + 4 = 25.
25 + 4 = 29.
29 + 4 = 33.
33 + 4 = 37.

21+4=25.
25-7=18.
18+11(7+11)=29.
29+4=33.
33-15=18.
18+19(15+4)=37.
37+4=41.
25-7=18.
18+11(7+11)=29.
29+4=33.
33-15=18.
18+19(15+4)=37.
37+4=41.
