Q: First prime of the form $x_i$ for $x_0=658$ and $x_i=1+2x_{i-1}$

Roland BacherGiven an initial integer $x_0>0$, one can consider the first prime of the recursive sequence $x_i=1+2x_{i-1}$. Naïvely such a prime should exist for $x_0$ arbitrary since the sequence $\log(x_i)$ is asymptotically an arithmetic progression. Sometimes it takes however some time: for $x_0=147$ my M...

I second the proposal for a 'procastination' tag. That's what I am doing at this very moment. — pinaki yesterday
