Finding The Value of N when Nth Term and AP is Given: To find the value of N we will first find the common difference and will then use the formula for the general term.
Example : Which term of the AP : 21, 18, 15,.....is- 81? Also, is any term 0? Give reason for your answer.
Solution : Here, a= 21 and and we have to find n.
as
So the common difference = -3
As
we have
So,
Therefore, the 35th term of the given AP is -81
Next, we want to know if there is any n for which . If such an n is there, then
i.e.,
i.e.,
So, the eighth term is 0.
For an AP , the first term is x, the common difference is y and the nth term is z. Which of the following expressions is the value of n? | |||
