WebJust use the standard form -> nth term= a1 + (n-1)* (D) in this case. 100th= 15 + (100-1) (-6) 100th= -579. where d is the common difference, a1 is the first term and n is the number of terms, then you'll never loose track of … WebJun 3, 2012 · You correctly deduced the 1st term, and could find the nth term iteratively, if necessary. Using the same method that you did for $a_1$, calculate $S_2, S_3,$ and $S_4$ and use your formula $a_n=S_n-S_ {n-1}$ to find the rest.
