Pattern
1st series: 6 -------- 9 -------- 18 ----------- 45 ----------- 135
x1.5 x2 x2.5 x3
2nd series: 20 ------ W -------- X ----------- Y ------------- Z
30 60 150 450
W = 20 x 1.5
X = W x 2
Y = X x 2.5
Find the value of R in the series 21, 25, 34, 50, R, 111.
65

21+22 = 25
25+32 = 34
34+42 = 50
50+52 = 75
75+62 = 111
So, value of R is 75.

First term = 2
Second term = 2x3+5 = 11
Third term = 11x4-6 = 38
Fourth term = 38x5+7 =197
Fifth term = 197x6-8 =1174
So, 1172 is the odd one.
