Answer: Add the equations to eliminate k

Step-by-step explanation:

Adding the equations, you get 2b=18, which you can solve for b. Afterward, you can substitute this value of b back into either equation to solve for k.

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
