Algebra.Com's Answer #767203 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "I'll give you a bit of help so that YOU can find the answers to the questions.... \n" ); document.write( "(a) The n-th term is the difference between the sum of the first n terms and the sum of the first (n-1) terms. Both those sums are given to you. \n" ); document.write( "(b) The difference of 56-48=8 between the 3rd and 5th terms allows you to determine the common difference between terms. \n" ); document.write( "Now you know the 3rd and 5th terms (given), the n-th term (from part a), and the common difference (from part b). That allows you to completely determine the sequence, allowing you to answer the remaining questions. \n" ); document.write( " |
