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.

(21+4), 18 = 25,18
(25+4), 18 = 29,18
(29+4), 18 = 33,18
(33+4),18 = 37,18
So the answer is 37, 18.
(25+4), 18 = 29,18
(29+4), 18 = 33,18
(33+4),18 = 37,18
So the answer is 37, 18.
