Find The Value of Common Difference when Nth Term, Number of Terms and First Term are Given
Find The Value of Commom Difference When Nth Term, N and the Fist Term Is Given.: We will use the formula for the general term. Putting the value of n , a and Nth Term we will find d.
Example: Find the common diffrenece when the first term of an AP is 3 the 16th term of the AP is 78.
Solution : Here, a= 3, n= 16 and
We have
So,
78 = 3+15 X d
15d = 75
d = 5
Therefore , the common difference d= 5.
Example: Distance between Ambala and Delhi is 200 Km. A person started from Ambala and traveled 50 Km on the fisrt day. How much Km shoul he travel daily so than he reaches Delhi in 16 days.
Solution: a= 50
d= ?
