E Correct answer
Explanation

The correct answer is E (None of these) because the series follows: 45×2+1=91, 91×4-1=363, 363×8-9=2905, 2905×16-7=46473. The last term 46478 is wrong, but since it's not listed as an option A-D, E is correct. The pattern involves multiplying by increasing powers of 2 and subtracting decreasing primes.
