Question

Which off the following represents the general term for the sequence 1, 3, 5, 7, 9, ...?

Answer 1

The general term for the sequence is n+2.

Answer 2

Answer:

2n-1

Step-by-step explanation:

We are given a sequence:

  1,3,5,7,9,...

We are asked its general term

Clearly this is a series of odd numbers

So, the general term is  2n-1

n=1  i.e. first term = 2-1=1

n=2  second term=4-1=3

n=3   third term= 6-1=5

and so on

Hence, general term of the sequence 1,3,5,7,9,... is:

    2n-1
