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 $x$
3, 5, 7... 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
