Hope my answer would be a great help for you.

Answer with Step-by-step explanation:

We are given a polynomial:

[tex]18x + 2x^3 - 3x^2 + 10[/tex]

We have to arrange it in descending order and then identify its third term

Polynomial in descending order is:

[tex]2x^3-3x^2+18x+10[/tex]

As we can clearly see the third term is:

18x

Hence,

Polynomial in descending order is:

[tex]2x^3-3x^2+18x+10[/tex]

and the third term is:

18x
