Question

34,124,205,277,340,394?,475

Answer 1

Answer:

439

Step-by-step explanation:

This is from Number Series of reasoning.

let's take the difference of consecutive terms.

given series is

34 , 124 , 205 , 277 , 340 , 394 , ? , 475

90. 81. 72. 63. 54... so on

I have written first set of differences..

124-34=90

205-124=81

....... so on

now difference of difference is 9

hope you get it..( 90-9=81,81-9=72,...so on..)

so difference between 394 and required term is 45

Required number is 394+45=439

if this is completely new to you,

34+90=124 ; 124+81=205....
