Arecursive rule for a geometric sequence is a1=49; an=3an−1 . what is the explicit rule for this sequence? enter your answer in the box. an=

Answer :

Explicit rule is

Step-by-step explanation:

A recursive rule for a geometric sequence is a1=49;an=3an−1

First term a1= 49

To get second term, multiply the first term by 3

So common ratio = 3

Explicit rule for geometric sequence is

Where a1 is the first term

r is the common ratio

a1= 49  and r= 3

5+2x=a

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
