Find the value of Y in the given series.
6, 9, 18, 45, 135
20, W, X, Y, 450
Both the series follow the same pattern.

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
75
85
95
21+22 = 25
25+32 = 34
34+42 = 50
50+52 = 75
75+62 = 111
So, value of R is 75.
Find the odd one out in the series 19, 29, 40, 44, 51, 59.
40
44
51
59
Given: 19 -------- 29 --------- 40 --------- 44 ----------- 51 ---------- 59
+(1+9) +(2+9) +(4+0) +(4+4) +(5+2)
Result: 19 ------- 29 --------- 40 ---------- 44 ---------- 52 ----------- 59
So, 51 is the odd one.
Find the odd one out in the series 4, 2, 3.5, 7.5, 26,25.
2
3.5
7.5
26.25
First term = 4
Second term = 4x0.5 = 2
Third term = 2x1.5 = 3
Fourth term = 3x2.5 = 7.5
Fifth term = 7.5x3.5 = 26.25
So, 3.5 is the odd one.
Find the odd one out in the given series 2, 11, 38, 197, 1172.
11
197
1172
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.
