Answer:

The center is (0,-5) and the radius is 9

Step-by-step explanation:

The equation of a circle can be given by

(x-h)^2 + (y-k) ^2 = r^2

where (h,k) is the center and r is the radius

(x-0)^2 + (y- -5) ^2 = 9^2

The center is (0,-5) and the radius is 9

3, 10, 17, 24. what is the 50th term in the sequence
Kamila [148]
Check if you can write an equation relating the term number to the actual value
n1=3
n2=10 = 3+7
n3= 17 = n2+7 = n1+7+7 = n1 +2*7
n4= 24 = n1+3*7

so you will notice a pattern
for the x-th term

n_x =3+(x-1)*7

the 50th term would be n_50 = 3+(50-1) * 7
