Find an explicit formula for the arithmetic sequence -45,-30,-15,0...

Answers

Answer:

15(n-1)-45

Step-by-step explanation:

Increases by 15, so sequence is arithmetic, and goes to positive.

1st term is -45

so 15(n-1) gives us first term.

Reply for any questions I got you

$\bf -45~~,~~\stackrel{-45+15}{-30}~~,~~\stackrel{-30+15}{-15}~~,~~\stackrel{-15+15}{0}~\hspace{7em}\stackrel{\textit{common difference}}{d=15} \n\n[-0.35em] ~\dotfill\n\n n^(th)\textit{ term of an arithmetic sequence} \n\n a_n=a_1+(n-1)d\qquad \begin{cases} a_n=n^(th)\ term\n n=\textit{term position}\n a_1=\textit{first term}\n d=\textit{common difference}\n \cline{1-1} a_1=-45\n d=15 \end{cases} \n\n\n a_n=-45+(n-1)15\implies a_n=-45+15n-15\implies a_n=15n-60$
