Select the option that will fill in the blank and complete the given series
51
The differences between consecutive terms form the sequence of consecutive odd numbers:
\(100-99=1,\ 99-96=3,\ 96-91=5,\ 91-84=7,\ 84-75=9,\ 75-64=11\)
The next subtraction is \(13\), so the missing term is:
\(64-13=51\)
Therefore the answer is 51.
