Write the first three terms in the following sequences. Identify them as arithmetic or geometric

Answer:

$A(1)=9$

$A(2)=4$

$A(3)=-1$

Arithmetic sequence

Step-by-step explanation:

We are given that

$A(n+1)=A(n)-5 \;for\;n\geq 1$ A(1)=9

We have to find first three terms and identify the sequence is geometric or arithmetic.

Substitute n=1

Then, we get

$A(2)=A(1)-5=9-5=4$

For n=2

$A(3)=A(2)-5=4-5=-1$

For n=3

$A(4)=-1-5=-6$

$d_1=A_2-A_1=4-9=-5$

$d_2=A_3-A_2=-1-4=-5$

$d_3=A_4-A_3=-6+1=-5$

$d_1=d_2=d_3=-5$

When the difference of consecutive terms are constant then the sequence is arithmetic sequence.

Therefore, given sequence is arithmetic sequence.

<h3>answer:</h3>

$r - 1$

<h3>Step by step explanation:</h3>

<h3> Step 1: Distribute</h3>

$( - r - 5) - ( - 2r - 4) \\ ( - r - 5) + 2r + 4$

<h3>Step 2: Eliminate redundant parenthesis</h3>

$( - r - 5) + 2r + 4 \\ - r - 5 + 2r + 4$

<h3>Step 3: Add numbers</h3>

$- 3 \purple{ - 5} + 2r + \purple{4} \\ - r \purple{ - 1} + 2r$

<h3>Step 4:Combine like terms </h3>

$\purple{ - r } - 1 + \purple{2r} \\ \purple{1r} - 1$

<h3>Step 5:Multiply by 1</h3>

$1r - 1 \\ r - 1$

Hopefully it's help
