An arithmetic sequence is given for each question below whose initial term

**a**and common difference**d**are also given. What is the firth term?

(1)**a**= 6;**d**= -2

(2)**a**= sqrt{2};**d**= sqrt{2}

To find the nth term, $\displaystyle a_n$, in an arithmetic sequence, use the following formula:

$\displaystyle a_n=a_1+(n-1)d$, where the first term is $\displaystyle a_1$ and the common difference is $\displaystyle d$

(1) $\displaystyle a_5=6+(5-1)(-2)=??$

(2) $\displaystyle a_5=\sqrt{2}+(5-1)(\sqrt{2})=??$ - Oct 23rd 2008, 05:46 PMmagentaritaI get it...
