First series of words increased by 3,
i.e, 8+3 = 11,
11+3 = 14,
14+3 = 17,
17+3 = 20

And second series of words are increased by 5.
i.e,
7+5 = 12,
12+5 = 17,
17+5 = 22.

There are two series ( 8,11,14, 17, 20) and ( 7, 12, 17, 22) increasing by 3 and 5 respectively.
8 + 3 = 11
11 + 3 = 14
14 + 3 = 17
17 + 3 = 20 => correct option.
And,
(7 , 12, 17, 22)
7+5= 12.
5+12= 17,
17+ 22 = 39.

So the right answer is 20.
Therefore B is the right option.

11 + 5 = 17.
17 + 5 = 22.
22 + 5 = 27.

2*1=2,
2*2=4+1 = 5,
2*5=10-1 = 9,
2*9=18+1 = 19,
2*19=38-1 = 37,
2*37=74+1 = 75.

All differ by 3 and 5.
23 + 27 = 40 ÷ 2 (average),
= 20.
