Answer:
405
Step-by-step explanation:
You only need to multiple 45 by 9 and get 405.
Hope this helps mostly wrong but i tried
Answer:
8
Step-by-step explanation:
- m = (Y2-Y1) ÷ (X2- X1)
- 2 = (10-c) ÷ (-1-(-2))
- 2 = (10-c) ÷( 1)
- 2= 10-c
- c = 10-2
- c= 8

450= (3000) r (3)
450=9000r 450/9000=9000r 0.05=r
Part (a)
This sequence is arithmetic because we are adding 4 to each term to get the next term. Nice work on getting the correct answer here.
To get the nth term of an arithmetic sequence, we'll use the formula below
an = a + d(n-1)
In this case, a = 14 is the first term and d = 4 is the common difference
So we have these steps
an = a + d(n-1)
an = 14 + 4(n-1)
an = 14 + 4n - 4
an = 4n + 10
Answer: 4n + 10
============================================
Part (b)
This sequence is geometric since we multiply each term by 4
The common ratio is r = 4 and the start term is a = 2.
So the nth term is....
an = a*(r)^(n-1)
an = 2*(4)^(n-1)
Answer: 2*(4)^(n-1)
