(4, 24)

42+4×2 = 16+8 = 24

and

(11, 143)

112+11×2 = 121+22 = 143

Now, check options-

(a) (9.102)

92+9×2 = 81+18 = 99

So, its not correct.

(b) (7, 42)

72+7×2 = 49+14 = 63

So, its not correct.

(c) (5, 40)

52+5×2 = 25+10 = 35

So, its not correct.

(d) (2, 8)

22+2×2 = 4+4 = 8

So, its correct
Thus, correct option is (d).
