The first sequence is cube numbers \"1%5E3\", \"2%5E3\", \"3%5E3\", \"4%5E3\" so the next number would be \"5%5E3=125\".
\n" ); document.write( "The second problem has a common difference of 5. Testing last two choices which contain 5n shows that the correct answer is 5n-7.
\n" ); document.write( "The common difference is -3 as each term is three less than its predecessor.
