7 + 4 = 11 + 8 = 19 + 16 = 35
the pattern seems to be to double the number that is added each time, thus the next term is
35 + 32 =67
and the one after that
67 + 64 = 131

3467910 is a single number: it is not a pattern!
Look at the difference between each number and the next number.
The next number is -21
The next number in the series 1 2 4 8 10 20 22 is
59 is the next number in this series.
The next number in the series is 67.
A single number such as 61205041320 does not make a series.
A single number, such as 12848384 does not make a series.
One number does not make a sequence (nor a series).
There is no series of number: just one very large number!
