a sequence has a first number of 3 and a half common difference of 4 what is the recursive rule of nth term

ELEN [110]

Answer:

$f(n) = f(n-1) + 8$ for $n > 1$

Step-by-step explanation:

Given

$f(1) = 3$ -- First Term

$\frac{1}{2}d = 4$ --- half common difference

Required

Find the recursive rule

First, we calculate the common difference

$\frac{1}{2}d = 4$

Multiply through by 2

$2 * \frac{1}{2}d = 2 * 4$

$d = 8$

The second term of the sequence is:

$f(2) = 3 + 8 = 11$

The third term is:

$f(3) = 11 + 8 = 20$

So, we have:

$f(1) = 3$

$f(2) = 3 + 8$

Substitute f(1) for 3

$f(2) = f(1) + 8$

Express 1 as 2 - 1

$f(2) = f(2-1) + 8$

Substitute n for 2

$f(n) = f(n-1) + 8$

Similarly:

$f(3) = 11 + 8$

Substitute f(2) for 11

$f(3) = f(2) + 8$

Express 2 as 3 - 1

$f(3) = f(3-1) + 8$

Substitute n for 3

$f(n) = f(n-1) + 8$

Hence, the recursive is:

$f(n) = f(n-1) + 8$ for $n > 1$

What are the two consecutive numbers of 235

Evgesh-ka [11]

Answer:

117, 118

Step-by-step explanation:

if 2 consecutive numbers have a sum of 235, then

Let the 2 numbers be n and n+1

Given That:

n + n+1 = 235

Simplify and solve:

2n + 1 - 235

2n = 234

n = 117.

If n = 117, then n +1 = 118. These are the 2 consecutive numbers.

Hope this helps.

Good Luck

After a 30% discount, an item was sold for $15,750. What was the original price of the item?

serious [3.7K]

Answer:

Step-by-step explanation:

Hi there,

To get started, set up a relationship:

$x$ ⇒$15,750

We know some original price was reduced to 15,750. The discount is 30%, and discounts are done by taking that % of the original price off, or subtracted. So, you are taking a price and subtracting a certain percentage off:

$x-0.3x=0.7x$ 30% is same as 0.3. In other words, the discounted price is 70% of the original value.

Now, let's set up an equation:

$0.7x=15,750$ Divide both sides by 0.7 to isolate x:

$x=\frac{15750}{0.7} =22,500$ The original price was $22,500.
