Question

Complete the series 6,27,128,------,3130

Answer 1

6*5-3=27
27*5-7=128
128*5-11=629
629*5-15=3130
The answer is 629

Answer 2

Answer:

The answer is 629.

Step-by-step explanation:

27 is obtained by : previous number × 5 - 3

                              = 6 × 5 - 3

                              = 30 - 3 = 27

128 is obtained by : previous number × 5 - 7

                              = 27 × 5 - 7

                              = 135 - 7 = 128

So the next number will be : previous number × 5 - 11

                              = 128 × 5 - 11

                              = 640 - 11 = 629

Now checking the pattern of the series,

3130 is obtained by : previous number × 5 - 15

                              = 629 × 5 - 15

                              = 3145 - 15 = 3130

So, the required number in the series is 629

And the resulting series is : 6, 27, 128, 629, 3130
