Answer:
p=(t-s)/r
Step-by-step explanation:
This is an equation so all we have to do is solve backwards step by step:
rp+s=t
rp+s-s=t-s
rp/r=(t-s)/r
p=(t-s)/r
Given:
The given arithmetic sequence is:
To find:
The recursive formula of the given arithmetic sequence.
Solution:
We have,
Here, the first term is -3. So, 
.
The common difference is:
The recursive formula of an arithmetic sequence is:
Where, d is the common difference.
Putting , we get
Therefore, the recursive formula of the given arithmetic sequence is , where .
Answer:
11 and 12
Step-by-step explanation:
x=smaller
y=larger
2y=3x-9 x+1=y
2(x+1)=3x-9
2x+2=3x-9
11=x
11+1=y
12=y
Answer:
The factors are (x - 1)(x - 5)(x + 2).
Step-by-step explanation:
Long division:
x - 5 )x^3 - 4x^2 - 7x + 10( x^2 + x - 2 <--------- Quotient.
x^3 - 5x^2
x^2 - 7x
x^2 - 5x
- 2x + 10
-2x + 10
...........
x^ 2 + x - 2 = (x + 2)(x - 1).
Answer:
39⇒3
52⇒4
130⇒10
Step-by-step explanation:
