Solution
(A)
8 + 5 = 13
13 + 8 = 21
21 + 11 = 32
32 + 14 = 46
46 + 17 = 63
63 + 20 = 83
Thus, (A) matches with (III)
(B)
This is an example of an ALTERNATE SERIES.
One is going as 20 -> 30 -> 40 -> 50
And, the other part is going as 80 -> 60 -> 40 -> 20.
Thus, (B) matches with (I)
(C)
0 + 2 = 2
2 + 1 = 3
3 + 2 = 5
5 + 3 = 8
8 + 2 = 10
10 + 5 = 15
15 + 2 = 17
17 + 7 =24
24 + 2 = 26
26 + 9 = 35
Thus, (C) matches with (IV)
(D)
6 * 2 + 1 = 13
13 * 2 - 1 = 25
25 * 2 + 1 = 51
51 *2 - 1 = 101
Thus, (D) matches with (II)
