Usimov [2.4K]4 years ago
8 0

Answer:

aₙ = a₁ . 5⁽ⁿ⁻¹⁾

Step-by-step explanation:

The first term in the sequence is a₁ = 6.

a₂ = 30. a₃ = 150.

We see that each consecutive term is multiplies by 5 to arrive at the next term.

That is: a₂ = 30 = a₁ . $ 5^{2 - 1}  = 5 $ = 6.5 = 30.

Similarly, a₃ = 150 = 6 $ \times $ $ 5^{3 - 1} = 5^2 = 25 $

Generalizing this, we have:

aₙ = a₁ . $ 5^{n - 1} $

This is called the recursive formula of the sequence.

Use a bar model to find the unknown value: 3/6 = ?/7
Lelechka [254]
This is set up as a proportion, so let’s cross multiply the values. When you do, you should get 21 = 6x. Now, divide each side by 6 to isolate the “x”. 21/6 is 3.5. x = 3.5. The unknown value is 3.5.

What is the greatest common factor of the numerator and denominator
Aloiza [94]

In the numerator, we can pull a 7 out of the expression 7x + 14 to get the product 7(x + 2). In the denominator, we can factor the expression 2x² + x - 6 like this:

2x^2+x-6=2x^2+4x-3x-6\\=2x(x+2)-3(x+2)\\=(x+2)(2x-3)

Our fraction can now be written as

\dfrac{7(x+2)}{(x+2)(2x-3)}

the only factor the numerator and denominator share in this case is x + 2.
