The recursive rule for a sequence is shown.

Mathematics
1 answer:

Given that the recursive formula is:
an=an-1+7
first term is
a1=17
the second term will be:
a2=a(2-1)+7
a2=a1+7
a2=17+7
a2=24
To evaluate for the explicit formula we use the formula:
an=a+d(n-1)
where
a=first term
d=common difference
from the calculations above:
d=24-17=7
thus the explicit formula will be:
an=17+7(n-1)
an=17+7n-7
an=7n+17-7
an=7n+10

Answer: B] an=7n+10

Can someone help me thanks
Helga [31]

Answer:

-142

Step-by-step explanation:

So we have the function:

f(x)=-x^2-9x+20

To find f(9), substitute x for 9:

f(9)=-(9)^2-9(9)+20

Square the first term and multiply the second:

f(9)=-81-81+20

Add:

f(9)=-142

And that's our answer :)

PLEASE HELP
maxonik [38]

Answer:

Step-by-step explanation:

An exponential function is of the form

y=ar^x

Where y=final amount, a=initial amount, r=common ratio or rate, x= term number or time

Since y(0)=2, a=2

The common ratio or rate is 10/2=5, so the exponential equation here is

y(x)=2(5^x)

The table would be

y(2)=50, y(3)=250, y(4)=1250

In terms of (x,y) rows

2,50

3,250

4,1250
