Question

Can You help me get this answer algebra 2?

Answer 1

The answer for the first sequence will be d = 0.1, $a_n=a_{n-1}+0.1$ and a₁ = 4

The answer for the second sequence will be d = -3 $a_n=a_{n-1}-3$ and a₁ = --1.

What is an arithmetic sequence?

An arithmetic sequence is a series of numbers in which the difference between the next term to its previous term remains constant for the whole series. This difference is called a common difference.

The solution for the first series will be:-

4,4.1,4.2,4.3,4.4

Common difference d = 4.1-4 = 0.1

$a_n=a_{n-1}+0.1$

First-term will be a₁ = 4.

The solution for the second series will be:-

-1,-4,-7,-10

Common difference d = -4-(-1)= -3

$a_n=a_{n-1}-3$

First-term will be a₁ = -1.

Therefore the answer for the first sequence will be d = 0.1, $a_n=a_{n-1}+0.1$ and a₁ = 4 and the answer for the second sequence will be d = -3 $a_n=a_{n-1}-3$ and a₁ = --1.
