Question
Find the 10th term of the AP 1,4, 7, 10….
Solution
In this problem, we are given different A.P. and we need to find the required term of that A.P.
10th term of the A.P. 1,4, 7, 10….
Here
First term (a) = 1
Common difference of the A.P. (d) = 4 - 1
= 3
Now, as we know,
`a_n = a + (n - 1)d`
So, for 10th term,
`a_10 = a + (10 - 1)d`
`= 1 + (9)3`
= 1 + 27
= 28
Therefore, the 10th term of the given A.P. is `a_10 = 28`
