Question

Which of the following given sequences can be represented as a polynomial in one variable?

• A. x - a
• B. 2x - b
• C. 3x - c
• D. bx - 2

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A

x - a

B

2x - b

C

3x - c

D

bx - 2

1, 2, 3... sequence can be represented using the polynomial $x$.
1, 3, 5... sequence​ can be represented using the polynomial $2x+1$.
2, 4, 6... sequence​can be represented using the polynomial $2x$.
1, 4, 9... sequence​can be represented using the polynomial $x^2$.

All of these are polynomials in one variable i.e., x.
