1. (B) 90

Explanation:-
20 + 12 = 32,  32 + 13 = 45, 45 + 14 = 59,  59 + 15 = 74,   Same as,   74 + 16 = 90.

Then, the next term is 90.

Hence, the correct answer is option (B) 90.

2.  (C) 85

Explanation:-
210 – 15 = 195,  195 – (15 + 5) = 195 – 20
= 175,
175 – (20 + 5)
= 175 – 25
= 150,
150 – (25 + 5)
= 150 – 30
= 120,
120 – (30 + 5)
= 120 – 35
= 85,

Then, the next next term is 85.

Hence, the correct answer is option (C) 85.

3.  (A) 52

Explanation:-
3 + 2 = 5  & 5 x 2 = 10,  10  + 2 = 12  &  12 x 2 = 24,   24 + 2 = 26  & 26 x 2 = 52.

Then, the next term is 52.

Hence, the correct answer is option (A) 52.

4.  (B) 48

Explanation:-
3 + 5 = 8,  8 + (5 + 2)  = 8 + 7 => 15,
15 + (7 + 2) => 15 + 9 = 24,
24 + (9 + 2) = 24 + 11 => 35,
35 + (11 + 2) = 35 + 13 => 48.

Then, the next term is 48.

Hence, the correct answer is option (B) 48.

5.  (D) 445

Explanation:-
5 x 3 + 1 = 15 + 1
= 16,
16 x 3 + 1 = 48 + 1
= 49,
49 x 3 + 1 = 147 + 1
= 148,
148 x 3 + 1 = 444 + 1
= 445.

Then, the next term is 445.

Hence, the correct answer is option (D) 445.
