8,11,14,17,20,..answer 23.
7,12,17,22,.... answer 27.

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

Another possibility is there are 3 series (8,7,11), (12,14,17) & (17,22,--)

Difference between first number of each series are 4,5.

Difference between second number of each series are 7,8.

So last number of each series can be

11, 17((last number of series 1)+6), 24 ((last number of series 2)+7).

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 2 series.

(8, 11, 14, 17, ?) with difference of 3.

(7, 12, 17, 22) with difference of 5.

So we have to find out series with diference 3.

Separate the given series in these two ways, you can get your answer.

@Rohit.

Answer. 75.

Because +1, -1 = 74 + 1= 75.

Randon said:   7 years ago
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.

8 + 5 = 11.
11 + 5 = 17.
17 + 5 = 22.
22 + 5 = 27.
