Choose the most appropriate option ( a ), ( b ) , ( c ) or (d)The nth ...
This is clearly an arithmetic sequence because the terms differ by 2 each time.
To find the nth term rule we need:
a value for the *first term , a
and a value for the *common difference d .
These values are then plugged into the formula:

Solution:
To find the nth term of the sequence 1, 3, 5, 7, ...
We can observe that each term in the sequence is obtained by adding 2 to the previous term.
So, the nth term can be represented as:
nth term = a + (n-1)d
where a = 1 (the first term), d = 2 (the common difference), and n is the term number we want to find.
Substituting the values, we get:
nth term = 1 + (n-1)2
Simplifying, we get:
nth term = 2n - 1
Therefore, the correct option is (b) 2n - 1.
