I don't know how the middle number is related but I have observed 1 pattern In the first figure, 21-18 = 20-17 =3 In the second figure, 8-1 = 19-12 = 7 In the third figure, 24-17 = 23-16 = 7 Also in Figure 1, 21-20 = 18-17 = 1 In Figure 2, 19-8 = 12-1 = 11 In Figure 3, 24-23 = 17-16 = 1 I hope someone can figure out the relation

## Ans 4:

Class : Class 10
Also 18+20 = 21+17=38 in Figure 1 In figure 2 1+19 = 12+8 = 20 In figure 3 24+16 = 17+23 = 40

## Ans 5:

Class : Class 10
