Answer:

A)100 in

Step-by-step explanation:

Given: Radius of circular table= 16 inches

Now, solving for circumference of the tabletop.

Remember, circumference of circle= $2\pi r$

we know pi= 3.14

∴ Circumference= $2\times 3.14\times 16$

⇒ Circumference of circular tabletop= 100.48 in ≅ $100\ in$

∴ Circumference of circular tabletop is 100 in.

The sum of the first n terms of an arithmetic sequence is n/2(4n + 20).

lesantik [10]

Answer:

(a).

$S_{n} = \frac{n}{2} (4n + 20) \\ \\S _{n - 1} = \frac{(n - 1)}{2} (4n - 4 + 20) \\ \\ S _{n - 1} = \frac{(n - 1)}{2} (4n + 16) \\ \\S _{n - 1} = \frac{(n - 1)(4n + 16)}{2} \\ \\ { \boxed{S _{n - 1} = {2 {n}^{2} + 6n - 8}}} \\$

(b).

from general equation:

$S _{n - 1} = \frac{(n - 1)}{2} (4n + 16)$

first term is 4n

common difference:

$16 = \{(n - 1) - 1 \}d \\ 16 = (n - 2)d \\ d = \frac{16}{n - 2}$
