53 comes next no

Answer 2

Answer:

53 is the correct response.

Given:

3, 9, 17, 27, 39, ______

To find:

the number that completes the series

Solution:

here, we have been given an incomplete series and we need to find out the missing number. on careful observation of the given series, we can see that each predecessive number of the series decreases by multiples of 2:

9 - ( 2 x 3 ) = 3

17 - ( 2 x4 ) = 9

27 - ( 2 x5 ) = 17

39 - ( 2 x6 ) = 27

now, let the missing number be Y

Y - ( 2 x7 ) = 39

Y - 14 = 39

Y = 39 + 14

Y = 53

So the missing number is 53.

Hence, 53 is the correct answer.
