What are the first four terms of the sequence given by the formula below? \n" ); document.write( "a_n=-2n+4 \n" ); document.write( "1st: -2+4 = 2 \n" ); document.write( "2nd: -4+4 = 0 \n" ); document.write( "3rd: -6+4 = -2 \n" ); document.write( "4th: -8+4 = -4 \n" ); document.write( "-------------------------- \n" ); document.write( "2. What is the 8th term of the sequence given by a_n=3n-5? \n" ); document.write( "a(8) = 3*8-5 = 19 \n" ); document.write( "----------------------- \n" ); document.write( "3.Write a recursive definition for the sequence below: \n" ); document.write( "-1, 4, 9, 14 \n" ); document.write( "Note: a(1) = -1, common difference = 5 \n" ); document.write( "a(n) = -1 + 5(n-1) = 5n-6 \n" ); document.write( "----------------------- \n" ); document.write( "4.
