Find a formula for the general term of the sequence 5 3 , − 6 9 , 7 27 , − 8 81 , 9 243 , assuming that the pattern of the first

Mkey [24]

Answer:

The formula to the sequence

5/3, -6/9, 7/27, -8/81, 9/243, ...

(-1)^n. (4 + n). 3^(-n)

For n = 1, 2, 3, ...

Step-by-step explanation:

The sequence is

5/3, - 6/9, 7/27, - 8/81, 9/243, ...

We notice the following

- That the numbers are alternating between - and +

- That the numerator of a number is one greater than the numerator of the preceding number. The first number being 5.

- That the denominator of a number is 3 raised to the power of (2 minus the position of the number)

Using these observations, we can write a formula for the sequence.

(-1)^n for n = 1, 2, 3, ... takes care of the alternation between + and -

(4 + n) for n = 1, 2, 3, ... takes care of the numerators 5, 6, 7, 8, ...

3^(-n) for n = 1, 2, 3, ... takes care of the denominators 3, 9, 27, 81, 243, ...

Combining these, we have the formula to be

(-1)^n. (4 + n). 3^(-n)

For n = 1, 2, 3, ...

Ernesto has $20 in an account. The interest rate is 10% compounded annually.

chubhunter [2.5K]

The interest Ernesto will earn in 1 year to the nearest cent is 2200 cents.

<u>Given the following data:</u>

Principal = $20.

Interest rate = 10%

Time = 1 year.

To calculate how much interest Ernesto will earn in 1 year to the nearest cent:

<h3>How to calculate compound interest.</h3>

Mathematically, compound interest is given by this formula:

$B=P(1+r)^t$

<u>Where:</u>

B is the balance.

P is the principal or starting amount.

R is the interest rate.

T is the time measured in years.

Substituting the given parameters into the formula, we have;

$B=20(1+0.1)^1\\\\B=20(1.1)$

B = $22.

<u>To cents:</u>

B = $22 \times 100$

B = 2200 cents.
