The algebraic form of an arithmetic sequence is 5n-2a) What is its common difference?​

Mathematics
1 answer:
Alexxandr [17]3 years ago
5 0

Answer:

5

Step-by-step explanation:

[math]

U_{n} = 5n - 2 \\

Common Difference = U_{n+1} - U_{n} \\

= [5(n + 1) - 2] - [5n - 2] = [5n + 5 - 2] - [5n - 2]\\

= 5n + 5 - 2 - 5n + 2\\

= 5

What is the sum of an infinite geometric series if 2=5 and r=1/3
Morgarella [4.7K]

Answer:

\frac{15}{2}

Step-by-step explanation:

The problem has a mistake, it should NOT be 2 = 5, rather a=5.

Now, given a = 5 (the first term is a), and

r = 1/3 (common ratio),

<em>we can solve for the sum of the infinite series by using the formula:</em>

<em>S_{\infty}=\frac{a}{1-r}</em>

<em />

Where S_{\infty} is the sum of the infinite geometric series,

a is the first term (given as 5), and

r is the common ratio ( r= 1/3 given)

<em>We now plug these into the formula and get our answer:</em>

<em>S_{\infty}=\frac{a}{1-r}\\=\frac{5}{1-\frac{1}{3}}\\=\frac{5}{\frac{2}{3}}\\=\frac{15}{2}</em>
