5 is increased by 2 to get 7
7 is increased by 2*2 to get 11
11 is increased by 222 to get 19
19 is increased by 222*2 to get 35
35 will increases by 22222 to get 67

67

The next number is anything you want. I found that series in a book I have, and the next number was 44.9831. But in a different book, the next number was 95.

67

67

11 is 5 times 2 minus 3.
19 is 11 times 2 minus 3.
therefore the numbers in the sequence are double the last number minus three, so 35 x 2 – 3 = 67
the other answers are also correct in saying that the pattern is also the previous number plus the next power of 2 going up from the first.

67 going by logic

a₁ = 5
a₂ = a₁ + 2
a₃ = a₂ + 4
a₄ = a₃ + 8
a₅ = a₄ + 16
a₆ = a₄ + 32 = 67

The differences are
2^1 , 2^2 , 2^3 , 2^4
So the nest will be 2^5 = 32
35 + 32 = 67 (The next number).

Just add the next power of 2.
5 + 2 = 7
7 + 4 = 11
11 + 8 = 19
19 + 16 = 35
35 + 32 = 67
