Find the 4th term from the end of the ap
WebIn the given problem, we need to find the 10 th term from the end for the given A.P. We have the A.P as 8, 10, 12 …126. Here, to find the 10 th term from the end let us first find the total number of terms. Let us take the total number of terms as n. So, First term (a) = 8. Last term (a n) = 126. Common difference (d) = =2. Now, as we know ... WebSolution: It is given that AP : -2, -4, -6,…., -100 First term (a) = -2, Common difference (d) = -4 - (-2) = -2 Last term (l) = -100 The nth term of an AP from the end a n = l - (n - 1 )d, where l is the last term d is the common difference. So the 12th term from the end, a 12 = -100 - (12 - 1) (-2) = -100 + (11) (2) = -100 + 22 = -78
