Find the Greatest Common Factor (GCF)

GCF = 2

Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

2(20t^2/2 + 14t/2 - 12/2)

Simplify each term in parenthesis

2(10t^2 + 7t - 6)

Split the second term in 10t^2 + 7t - 6 into two terms

2(10t^2 + 12t - 5t - 6)

Factor out common terms in the first two terms, then in the last two terms

2(2t(5t + 6) - (5t + 6))

Factor out the common term 5t + 6

Given a geometric sequence with a1 = 6 and r= 2/3 write an explicit formula for an the nth term of the sequence.

fomenos

the explicit formula for aₙ the nth term of the sequence will be: $a_{n}=6\times (\frac{2}{3})^{n-1}\\$

Step-by-step explanation:

The explicit formula of geometric sequence is of the form:

$a_{n}=a_{1}r^{n-1}$

where a₁ is the first term and r is the common ratio.

We are given:

a₁ = 6

r = 2/3

Putting values in the formula:

$a_{n}=a_{1}r^{r-1}\\a_{n}=6\times (\frac{2}{3})^{n-1}\\$

So, the explicit formula for aₙ the nth term of the sequence will be: $a_{n}=6\times (\frac{2}{3})^{n-1}\\$

Help me <br>ans should be well explained

nikdorinn [45]

Step-by-step explanation:

¡)

The lowest rank of the class is unknown to us.

Let's say, it's x.

highest marks =2 × lowest rank + 7

=> 87 = 2x + 7 (this is the equation we gotta solve)

=> 87 - 7 = 2x

=> 2x = 80

=> x = 40

And x is the lowest rank of the class, so we got the required answer.

$\boxed{ \mathfrak{lowest \: rank = \red{40}}}$

¡¡)

it can be 17 since the denominators are in increasing order and 17 only fits in.

I'm looking for any other pattern that can be present here.
