Answer:

The function will be: f(n) = 2n

Step-by-step explanation:

An arithmetic sequence is a sequence where the common difference between consecutive terms is same

The sequence according to given information is:

2,4,6...

Here

a_1 = 2

a_2 = 4

a_3 = 6

the common difference will be:

$d = a_2-a_1 = 4-2 = 2\\d = a_3-a_2 = 6-4 = 2$

The arithmetic sequence is given by:

$a_n = a_1+(n-1)d$

Putting the values

$a_n = 2+(n-1)(2)\\a_n = 2+2n-2\\a_n = 2n$

Hence,

The function will be: f(n) = 2n

Identify a solution of the equation: log2x+log(x−5)=2

Harrizon [31]

Answer:

3.x= 10

Step-by-step explanation:

log 2x + log (x - 5) = 2
log (2x(x - 5)) = 2
2x(x - 5) = 10²
2(x² - 5x) = 100
x² - 5x - 50 = 0
x² + 5x - 10x - 50 = 0
x(x + 5) - 10(x + 5) = 0
(x - 10)(x + 5) = 0
x = 10
x = -5, this root is discounted as log should be positive.

Correct choice is 3.
