A recursive formula is a function of the previous term. The "an-1" is the term that comes before "an".
an arithmetic sequence just adds or subtracts the same number (common difference, d) between terms. looking at the recursive formula it is -9
-35, -44, -53, -62, .....
The explicit formula is a function of the terms place "n" in the sequence. This is written as :
an = a1 + d(n-1)
fill in
a1 = -35 and d = -9
an = -35 - 9(n-1)
expand to
an = -35 - 9n + 9
an = -26 - 9n
For a f(x) = -2x + 10
for b f(x) = (2/3)x + 2
for b it should be pretty easy to make the graph of the line. you can see y-intercept and the slop is also easy to see.
for b the slope is easily determines and then I just hade to use the slope to figure out the y-intercept.
Step-by-step explanation:
<h3>
<em>Given </em></h3>
<em>p </em><em>=</em><em> </em><em>x </em><em>+</em><em> </em><em>y</em>
<em>When </em>
<em>x </em><em>=</em><em> </em><em>1</em><em>6</em><em> </em><em>,</em><em> </em><em>y </em><em>=</em><em> </em><em>8</em><em> </em><em>Then </em>
<em>p </em><em>=</em><em> </em><em>1</em><em>6</em><em> </em><em>+</em><em> </em><em>8</em><em> </em>
<em> </em><em> </em><em> </em><em>=</em><em> </em><em>2</em><em>4</em>
