Note - Refer to the attachment for better understanding.
☞ Lets , we observe the given pattern first . After observing carefully We found that,
In case 1 ,
➝ ( A + C) - (B + D)
➝ (9 + 8) - (7+5)
➝ 17 - 12
➝ 5.
☞ Hence we get the middle number same.
Similarly, we have to apply this trick in all the other two cases .
In case 2 ,
➝ ( A + C) - (B + D)
➝ (15 + 11) - (6 + 2)
➝ 26 - 8
➝ 18.
☞ Hence again we get the middle number same.
Now, applied this trick in case 3.
In case 3 ,
➝ ( A + C) - (B + D)
➝ (17 + 6) - (9 + 5)
➝ 23 - 14
➝ 9
☞ Hence the middle term in the third case is 9
that is the value of (?)
