Solve the number series questions given below:
4 19 49 94 154 ?
(a) 223
(b) 225
(c) 229
(d) 239
(e) None of these
Solution: (c)
The pattern of the number series is :
\(\displaystyle 4+1\times 15=19\)
\(\displaystyle 19+2\times 15=49\)
\(\displaystyle 49+3\times 15=94\)
\(\displaystyle 94+4\times 15=154\)
\(\displaystyle 154+5\times 15=229\)
101 103 99 105 97 ? 95
(a) 93
(b) 104
(c) 108
(d) 107
(e) None of these
Solution: (d)
The pattern of the number series is :
101 + 2 = 103
103 – 4 = 99
99 + 6 = 105
105 – 8 = 97
97 + 10 = 107
7 10 16 28 52 ? 196
(a) 100
(b) 90
(c) 160
(d) 150
(e) None of these
Solution: (a)
The pattern of the number series is :
7 + 3 = 10
\(\displaystyle 10+12=(2\times 3)=16\)
\(\displaystyle 16+12=(2\times 6)=28\)
\(\displaystyle 28+24=(2\times 12)=52\)
\(\displaystyle 52+48=(2\times 24)=100\)
1 2 6 21 ? 445 2676
(a) 88
(b) 77
(c) 52
(d) 64
(e) None of these
Solution: (a)
The pattern of the number series is as given below:
\(\displaystyle 1\times 1+1=2\)
\(\displaystyle 2\times 2+2=6\)
\(\displaystyle 6\times 3+3=21\)
\(\displaystyle 21\times 4+4=88\)
\(\displaystyle 88\times 5+5=445\)
10400 2600 650 ? 40.625 10.15625 2.5390625
(a) 175.5
(b) 162.5
(c) 154.75
(d) 156.25
(e) None of these
Solution: (b)
The pattern of the number series is as given below:
\(\displaystyle 10400\div 4=2600\)
\(\displaystyle 2600\div 4=650\)
\(\displaystyle 650\div 4=162.5\)
\(\displaystyle 162.5\div 4=40.625\)
\(\displaystyle 40.625\div 4=10.15625\)
