Question

What is the seventh term of an arithmetic sequence represented by the rule A(n) = 9+ (n 1)(-5)?

Answer 1

A linear equation in slope intercept form that passes through the points (-11 -5) and (1 -2) is:

$y=\frac{1}{4}x-\frac{9}{4}$

Step-by-step explanation:

Given:

Explicit formula for sequence

$A(n)=9+(n-1)(-5)$

To find the 7th term we have to put n=7

So,

$A(7)=9+(7-1)(-5)\\=9+(6)(-5)\\=9-30\\=-21$

A linear equation in slope intercept form that passes through the points (-11 -5) and (1 -2) is:

$y=\frac{1}{4}x-\frac{9}{4}$
