Given the arithmetic sequence an = 5 + 2(n − 1), what is the domain for n?

all integers
all integers where n ≥ 0
all integers where n > 1
all integers where n ≥ 1

someone me. you.

The domain for n is:

            All integers where n ≥ 1

We know that the domain is the collection of all the possible input values i.e. for which the function or sequence is well defined.

The arithmetic sequence is given by:

We know that the terms of the sequence is given by:

i.e. first term, second term and third term and so on.

Hence, n=1 i.e. it starts with the first term of the sequence.

                Hence, the answer is:

                All integers where n ≥ 1

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

i hope that is right.
