Find the fourth term of ap 2,7,12
Answers
Answer:
The fourth term is 17.
Step-by-step explanation:
The first term a is = 2
The common difference d is = 7-2 = 5
the fourth term would be = a+(n-1)*d ║ here n is = 4
= 2 + (4-1)*5
= 2+3*5
= 2+15
= 17
OR
As the third term is given i.e., 12
So we can find the fourth term by adding the third term with the common difference.
∴ Fourth term = 12+5
= 17
The above formula ( a+(n-1)*d ) can be used to find any term of the A.P. if the the first term and the common difference is given.
