What is the closed linear form for this sequence given a1 = 0.3 and an + 1 = an + 0.75?

german

Answer:

The closed linear form of the given sequence is $a_{n}=0.75n-0.45$

Step-by-step explanation:

Given that the first term $a_{1}=0.3$ and $a_{n+1}=a_{n}+0.75$

To find the closed linear form for the given sequence

The formula for arithmetic sequence is

$a_{n}=a_{1}+(n - 1)d$ (where d is the common difference)

The above equation is of the given form $a_{n+1}=a_{n}+0.75$

Comparing this we get d=0.75

With $a_{1}=0.3$ and d=0.75

We can substitute these values in $a_{n}=a_{1}+(n - 1)d$

$a_{n}=a_{1}+(n - 1)d$

$=0.3+(n-1)(0.75)$

$=0.3+0.75n-0.75$

$=-0.45+0.75n$

Rewritting as below

$=0.75n-0.45$

Therefore $a_{n}=0.75n-0.45$

Therefore the closed linear form of the given sequence is $a_{n}=0.75n-0.45$

18/X=2.4/28 find X plz help

yulyashka [42]

Cross multiply

18 / X = 2.4 / 28
so
18 * 28 = X (2.4)
and that becomes
504 = X * 2.4
then divide by 2.4
X = 210

Find the value of the expression: −0.5(7b−12a)−(8.4a−14b) if a=−10; b=−6.

ELEN [110]

Replace a and b in the equation with their values given:

-0.5(7(-6)-12(-10)-(8.4(-10)-14(-6))

Multiply within the parentheses

-0.5(-42 + 120) -(-84 + 84)

Add inside the parenthesis:

-0.5(78)-0

Multiply:

-.05 x 78 = -39

The answer is -39
