Answer:
<h3>dn = -7^n-1</h3>
Step-by-step explanation:
Given the sequence -1,-7,-49,-343,....
We are to find the nth term of the sequence
dn = ar^n-1
a is the first term = -1
r is the common ration = -7/-1 = -49/-7 = 7
n is the number of terms
Substitute
dn = -1(7)^n-1
dn = -7^n-1
hence the nth term of the sequence is dn = -7^n-1

Answer:
21
Step-by-step explanation:
The expression Jackie came up with is:
0.75m = 15.75.
To get the value of m, we divide both sides by 0.75
0.75m = 15.75.
0.75m/0.75 = 15.75/0.75
m = 1575/75
= 21
X/133 = 105/100 solve for x by using proportions
