Write an equation for the nth term of the arithmetic sequence. Then find a 30 -9, -6, - 3,0, ...

The nth term is given by:

The 30th term is 78.

Step-by-step explanation:

Arithmetic sequence:

The nth term of an arithmetic sequence is given by:

In which is the first term and d is the common difference between terms.

-9, -6, - 3,0

This means that . So

30th term:

The 30th term is 78.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

$6.42
