Isn’t it just 6.3. Because the the first power doesn’t change anything so it’s just 0.63 times 10 and that equals 6.3

Find a formula for the nth term in this arithmetic sequence:

Sati [7]

The nth term of the arithmetic sequence is Tn = -7 + ( n - 1) 6

<h3>What is an arithmetic sequence?</h3>

An arithmetic sequence is defined as a sequence of numbers where the differences between every two consecutive terms is the same through out the sequence.

The nth term of an arithmetic sequence is expressed as;

an = a + ( n - 1) d

Where;

a is the first term
n is the number of terms
d is the common difference

Substitute the values

an = -7 + ( n - 1) 6

Thus, the nth term of the arithmetic sequence is Tn = -7 + ( n - 1) 6

Last time, one out of every 4 students in our class was absent. This time, after Jen came back, only one out of every 5 students

VMariaS [17]

Answer: There are 20 students and 4 students are not here today.

Step-by-step explanation:

If the number of students = 4

Let the number of students be 'x'.

Fraction of students absent = $\dfrac{x}{4}$

If the number of students = 5

Fraction of students absent = $\dfrac{x}{5}$

And Jen came back,

So, the fraction of student absent is also written as

$\dfrac{x}{4}-1$

According to question, it becomes,

$\dfrac{x}{5}=\dfrac{x}{4}-1\\\\\dfrac{x}{5}=\dfrac{x-4}{4}\\\\4x=5(x-4)\\\\4x=5x-20\\\\4x-5x=-20\\\\-x=-20\\\\x=20$

Hence, there are 20 students in our school.

And number of students are not here today is $\dfrac{20}{5}=4$
