1. Answer : (a) 172

Explanation:-
7 + 1 x 11 = 7 + 11
= 18,
18 + 2 x 11 = 18 + 22
= 40,
40 + 3 x 11 = 40 + 33
= 73,
73 + 4 x 11 = 73 + 44
= 117,
117 + 5 x 11 = 117 + 55
= 172
Then, the next term is (a) 172.

Hence, the answer is (a) 172.

2.  Answer : (c) DINSX

Explanation:-
A + 1 = B,   F + 1 = G,  K + 1 = L,   P + 1 = Q,   U + 1 = V.
C + 1 = D,   H  + 1 = I,  M + 1 = N, R + 1 = S,   W + 1 = X.

Then, the next term is DINSX.

Hence, the answer is (c) DINSX.

3.  Answer : (d) 75

Explanation:-

3 + 1 x 2 = 3 + 2
= 5,
5 + 2 x 2 = 5 + 4
= 9,
9 + 2 x 3 = 9 + 6
= 15,
15 + 2 x 4 = 15 + 8
= 23,
23 + 2 x 5 = 23 + 10
= 33,
33 + 2 x 6 = 33  + 12
= 45,
45 + 2 x 7 = 45 + 14
= 59,
59 + 2 x 8 = 59 + 16
= 75.
Then, the next term is 75.

Hence, the answer is (d) 75.

4.  Answer : (b) SXI

Explanation:-

O  + 1  = P,              P + 1 = Q,             Q + 1 = R,     Same as,   R  + 1 = S,
T   + 1 = U,              U + 1 = V,              V  + 1 = W,                         W + 1 = X,
E   + 1 = F,                F + 1 = G,             G + 1 = H,                            H  + 1 = I.

Then, the next term is (b) SXI.

Hence, the answer is (b) SXI.

5.  Answer : (b) 94

Explanation:-
61 is the reverse place value of 16,
52  is the reverse place value of 25,
63 is the  reverse place value of 36.
49 is the reverse place value of 94.

Then, the next term is (b) 94.

Hence, the answer is (b) 94.
