**(A) Answer: (2) 252
Explanation:-**

198 + 2

^{2}= 202,

202 + 3

^{2}= 211,

211 + 4

^{2}= 227,

227 + 5

^{2}= 252

Hence, the answer is (2) 252.

**(B) Answer: (2) ER
Explanation:-**

A + 1 = B, N + 1 = O

B + 1 = C O + 1 = P

C + 1 = D P + 1 = Q

D + 1 = E Q + 1 = R

Hence, the answer is (2) ER.

(C) Answer: (2) 211

Explanation:-

2^{3} – 1 = 7

3^{3} – 2 = 25

4^{3} – 3 = 61

5^{3} – 4 = 121

6^{3} – 5 = 211

Hence, the answer is (2) 211

(D) Answer: (2) K – 11, M – 13.

Explanation:-

C + 2 = E, E + 2 = G, G + 2 = I, I + 2 = K, K + 2 = M

Hence, the answer is (2) K – 11, M – 13.
