The n-th term of an arithmetic progression can be written as: \n" ); document.write( "a_n = a + (n-1)d, where d is the common difference and a is the 1st term. \n" ); document.write( "We don't know where the numbers 3 and 34 lie in the sequence, but we know \n" ); document.write( "that their difference is 3d, since they are 3 places away from each other. \n" ); document.write( "So we have 3d = 31, or d = 31/3. \n" ); document.write( "Since consecutive terms differ by d, we have p = 3 + 31/3 = 40/3 and \n" ); document.write( "q = 40/3 + d = 40/3 + 31/3 = 71/3. \n" ); document.write( "So the four values in the sequence are 3, 40/3, 71/3, 34 \n" ); document.write( " \n" ); document.write( " |
