Algebra.Com's Answer #712439 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! If the first term is a and the common difference is d, then the sum of the first two terms is a + (a+d) = a+2d, and the 10th term is a+9d. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "That is a simple system of two linear equations. Solve them to find the values of a and d; then use a and d to find the values of the 5th and 6th terms. \n" ); document.write( " |
