What number comes next 5, 12, 26, 54,?

110, 222, 446

Step-by-step explanation:

12 - 5 = 7

26 - 12 = 14

54 - 26 = 28

The next number in this sequence is twice the difference between the previous two numbers in the sequence.

Therefore the next number should have a difference of

2

*

28

or

56

. We can therefore determine the next number by adding

56

to

54

to get

110

110 - 54 = 56

Therefore the next number in the sequence will have a difference of

2

*

56

or

112

.

110

+

112

is

222

222 - 110 = 112

Therefore the next number in the sequence will have a difference of

2

*

112

or

224

.

222

+

224

is

446
