Question

what will come in the place of question mark in the following series.? 2,6,20,42,?​

Answer 1

Answer:

70

Step-by-step explanation

2+4=6

6+14=20

20+22=42

now we need to find the difference between the no. we added to get the series

14-4=10

22-14=8

here we get one more series and that is 10,8,6 (sustracting 2 in each)

so, 22+6=28(from above series)

therefore we will add 28 to 42 to get our series completed

42+28=70
