The differences between consecutive terms are -2, -4, -8, -16, -32. These differences follow a pattern of doubling, so the next difference should be -32 * 2 = -64. Subtracting 64 from 795 gives 731.
The differences between consecutive terms are 2, 4, 8, 16, and 32, which are successive powers of 2. Following this pattern, the next difference must be 64. Subtracting 64 from 795 gives 731.
