Question

5,7,9,11... write the algebraic form?​

Answer 1

The expressions in which the numbers, or variables, or both, are connected by operational signs (+, - etc.) are called algebraic expressions. For example 5, 4x, a+b, x−y etc.

Answer 2

Answer:

2k+1

Step-by-step explanation:

The answer is 2k+1 where 'k' is any integer because,

(where k is 0)

2×0+1=1..........(1 is an odd no.)

(where k is 1)

2×1+1=3..........(3is an odd no.)

(where k is 2)

2×2+1=5.........(5 is an odd no.)

(where k is 3)

2×3+1=7..........(7 is an odd no.)

And so on........

Therefore, the algebraic form of odd numbers (1, 3, 5, 7......) is 2k+1.

Hope it helps :)
