WebSolution: The sum of n terms S n = 441 Similarly, S n-1 = 356 a = 13 d= n For an AP, S n = (n/2) [2a+ (n-1)d] Putting n = n-1 in above equation, l is the last term. It is also denoted by a n. The result obtained is: S n -S n-1 = a n So, 441-356 = a n a n = 85 = 13+ (n-1)d Since d=n, n (n-1) = 72 ⇒n 2 – n – 72= 0 Solving by factorization method, Web›H±•ÊªÐj¬ ~Üé;†S^0^ò¸`· È £ ÓëÝÅâ¦Y¾9 7Å` E7Ä ÷Ð ¦òa 8Å϶2Éu óé*žÚá+~6BØß þ‰Ä! ¥;QÏ®a R"YÛîò; Ý› ¯£Ñ Éú(® *ÿÁN™Ô²¼óÃÐG~ Å¿ÇV; 2ui\ªð¦ `‹™î7äÛèox¦sÕªU ÈmÄÙ6:Œv`ºÑf u··±–ƒf ßL¸Åðnö¯¼e—ÎÃN'V»rìý\Ý• V‡òÜ KMz ”ÎjŠ d ... the palo verde https://gftcourses.com
