Question 1059619: Find the first term, the common difference, and give a recursive formula do arithmetic sequence. 6th term is -10; 15 term is -46 Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! s6=-10
s15=-46
change of -36 in 9 terms, and the difference is -4.
s1 is 4(6) greater than s6 or -10+24=14
sn=14-4*n
First term is 14, common difference is -4
