In python for the absolute beginner, we have this (page 28):
"If an alien has 3 heads, grows 1 more than double his total number of
heads, how many heads does the alien have?"
My formula is: (3 * 2) + 1
(For example, in this sequence, each sequential number is one more than double the next one: 2, 5, 11, 23, 47.)
but he gives (3 + 1) * 2 = 8. But he says one more than double his (current) total. So that seems incorrect.
Who is right?
