Description for Correct answer:

21+22=21+4=25

25+32=25+9=34

34+42=34+16=50

50+52=50+25=75

75+62=75+36=111

111+72=111+49=160

Answer 2

Answer:

Step-by-step explanation:

25 - 21 = 4

34-25 = 9

50-34 = 16

? - 50 = X

111-? = y

160-111= 49

Now from the se Substractions we can see that there is a relation in the results (i.e. 4+5= 9,9 + 7 =16)

Similarly 16 + (7+2) = 16+ 9

16+9= 25

In place of X web can write 25

? - 50 = 25

? = 25+50 = 75 (answer)

Now if you want to check the answer, then

25-21 = 4

34- 25=9(4+5)

50-34= 16(9+7)

75-50= 25(16+9)

111-75 = 36 (25+11)

160-111= 49(36+13)
