Question

Find the next number in the the series 18, 42, 67, 93, _____

Answer 1

18+24=42
42+25=67
67+26=93
93+27=120

Answer 2

Answer:

The next number in series is 120

Step-by-step explanation:

Given series ,

18, 42, 67, 93, _____

Now,

Taking the first two number ( 18 , 42 )

Difference of both the numbers

= 42 - 18

= 24

Taking the next two numbers in order ( 42 , 67 )

= 67 - 42

= 25

Taking the next two numbers in order ( 67 , 93 )

Difference of both the numbers

= 93 - 67

= 26

So , The difference of two consecutive number in series are 24, 25 , 26

Therefore,

The next difference should be 27

Let the next number in series be x

So following the pattern,

x - 93 = 27

x = 27 + 93

x =   120

Hence,

The next number in series is 120

18, 42, 67, 93, 120
