<em><u>The GCF ( Greatest Common Factor ) of 12, 28, and 4 is 4</u></em>

Alja [10]3 years ago
5 0

Answer:

The greatest common factor of 12, 28, and 4 would be 4.

Step-by-step explanation:

We will now calculate the prime factors of 28 and 12, than find the greatest common factor (greatest common divisor (gcd) of the numbers by matching the biggest common factor of 28 and 12.

what is the explicit formula and recursive formula of the numbers 4,7,10,13,16...i don't even know how to start this problem. i
Lana71 [14]

An arithmetic sequence is a sequence with a constant

<span> increase or decrease also known as the </span>constant difference

In the sequence 10, 40, 70, 100, ….

The constant difference between the terms is 30

A recursive formula for a sequence would be:

a1= first term in the sequence

an = term you are trying to find

an-1 = previous term in the sequence

d = constant difference

Explicit Formulas: 

A formula that allows you to find the nth term of the sequence by substituting known values in the expression.

Formula : an = a1 + d( n - 1)

a1= first term in the sequence

an = current term in the sequence

d = constant difference

n = term number

Solution: 

<span>Write the explicit formula of the sequence 4, 7, 10, 13, 16 ….</span>

Formula for explicit term:

an = ___ + ___( n - 1)

Simplify: an = ___ + ___n

In the sequence 4, 7, 10, 13, ….

To find the 11th<span> term explicitly, I plug in the into the formula I just made:  </span>

an = 1 + 3n

a11<span> = 1 + 3(11)  </span> 

a11<span> = 34  </span>

Find the 15th term of the sequence using the formula: an = 1 + 3n

Write the recursive formula of the sequence 4, 7, 10, 13, ….

Recursive formula:

a1 =

an = a  n  - 1

In the sequence 4, 7, 10, 13, 16 ….

To find the 5th<span> term recursively, I plug it into the formula I just made:  </span>

<span>  a</span>n = an-1 + 3

a5 = a5-1<span> + 3   in words: 5</span>th<span>  term equals the 4</span>th term plus 3

a5<span> = 13 + 3  </span>

a5<span> = 16   </span>

Whats the common ratio of the sequence 7.04 Q14​
julsineya [31]

Answer:

\frac{1}{4}

Step-by-step explanation:

The given sequence is a geometric sequence.

We can find the common ratio using any two consecutive terms of the sequence.

r=\frac{\frac{-1}{10} }{\frac{x-2}{5} }=\frac{-1}{10}\times \frac{-5}{2}=\frac{1}{4}

The common ratio is \frac{1}{4}
