Arrange the following polynomial into descending order and identify the 3rd term.
18x + 2x3 − 3x2 + 10
18x
2x3
−3x2
10

In arranging the terms of this polynomial, take note of the exponents of the variables. The arrangement of this polynomial is,
                        2x³ - 3x² + 18x  - 10
Thus, the third term of this polynomial should be 18x which is the first choice.
