Answer 1

Step-by-step explanation:

The difference of the two consecutive numbers are 1, 4, 9, 16, 25, 35. Q: Choose the correct alternative which will complete the following series.

Answer 2

Answer:

4 on the 5th place.

Step-by-step explanation:

The series is in two parts:

0,_,2,_,4,_,12,_,20,_

Here, first 2 is added ,then leaving one digit 4,then 6 , 8 and so on

that is even number are added  leaving one digit.

so,

    0 + 2 =2

    2 + 4 =6

    6 + 6 =12

    12 + 8=20

but in the series instead of 6 it is 4 at 5th place

_,1,_,4,_,9,_,16,_,25

same way here odd numbers are added leaving one digit.
