Answer 1

Answer:

$a_1=4,a_2=6,a_3=8,a_4=10$

Step-by-step explanation:

We are given that a graph

We can see that point on the graph

(1,4),(2,6),(3,8),(4,10).

We have to find the arithmetic sequence

Sequence :It is that function which domain is natural set and range is real number .

Arithmetic sequence : It is that sequence in which difference between two consecutive terms are equal.

Sequence like as

$f(1),f(2),f(3),.. f(n)$

Or $a_1,a_2,a_3,...,a_n$

We have

$a_1=4,a_2=6,a_3=8,a_4=10$

Answer 2

The answer is 
First term: 2
Second Term: -2
Third: -6
Fourth: -10.
