Question

what is the next number in series of 2,35,104,209

Answer 1

Solution:

2,35,104,209…..

First find the difference of first from second number, third from second, fourth from third

35-2=33; 104-35=69; 209-104=105

Then Subtract the second value from the first value of the difference & third value from second value . In both the difference Common value is 36

69-33=36; 105-69=36;;

36+105=141

141+209=350

Hence, the missing number is 350.

Answer 2

Solution :-

2,  35,  104,  209

Difference between 2nd and 1st,  = 35  -  2  =  33

Between 3rd and 2nd = 104  -  35  =  69

Between 4th and 3rd = 209  -  104  =  105

Now, difference between the values obtained -

69 - 33 = 36  

105 - 69 = 36

It is clearly seen that the difference is increasing by 36.

So, the next number in the series will be = (105 + 36) + 209

 = 141 + 209

= 350

Hence, the next number in the series is 350
