Question

What is the next number of the following sequence 7, 14, 55, 110, _ ?

Answer 1

7 + 7 = 14

14 + 41 = 55

55 + 55 = 110

110 + 011 = 121 

Next number in the sequence = 121.

Answer 2

The sequence will be 7,14,55,110,121

The first number 7 is added to itself to give 14 .

Then, 14 is added to the reverse of itself to give 55 .

55 is added to itself to give 110 .

According to the question, we add 110 to the reverse of itself,that is 011 to get 121.

Thus, 121 will be the answer.
