What is the recursive formula for this geometric sequence 2, -10, 50, -250, .... ?
The recursive formula for this geometric sequence is:
= 2; = (-5) •
Step-by-step explanation:
To find the recursive formula for a geometric sequence:
- Determine if the sequence is geometric (Do you multiply, or divide, the same amount from one term to the next?)
- Find the common ratio. (The number you multiply or divide.)
- Create a recursive formula by stating the first term, and then stating the formula to be the common ratio times the previous term.
The recursive formula is:
= first term; = r • , where
- is the first term in the sequence
- is the term before the nth term
- r is the common ratio
∵ The geometric sequence is 2 , -10 , 50 , -250
∴ = 2
- To find r divide the 2nd term by the first term
∵
∴
- Substitute the values of and r in the formula above
∴ = 2; = (-5) •
The recursive formula for this geometric sequence is:
= 2; = (-5) •

Answer:
<em>i believe it would be 12</em>
Step-by-step explanation:
Anything to the zero power is 1. One times 12 gives you your grand answer of 12!
Because 585k > 500k, then the commission would be 6%.
Percent: 6% = 0.06
Now we will multiply the cost of the house by the percentage to find the commission amount:
1) 0.06(585,000) = 35,100
The total amount the agent will receive would be $35,100.
