WebIf the n th term of a progression is (4n−10) show that it is an AP. Find its common difference. Medium Solution Verified by Toppr Given n th term of AP is 4n−10 Putting … WebThe n t h term of an A.P, whose first terms is a and common difference is d, is T n = a + (n − 1) d Which can also be written as T n = (a − d) + n d On comparing this with the given n t h term, we get T n = (a − d) + n d = 4 n + 1 From this, we get a − d = 1 and d = 4 Therefore, first term, a = 5 and common difference d = 4.
Web12 aug. 2024 · The common difference of AP is p. Step-by-step explanation: It has been given that the nth term of an AP is pn +q. Mathematically, we can write. Common difference of an AP is the difference between two consecutive terms. We represent common difference as d. Thus, we have. Substituting n = 1 in (i) Substituting n = 2 in (i) … WebThe formula for finding the n-th term of an AP is: an = a + (n − 1) × d Where a = First term d = Common difference n = number of terms a n = nth term Example: Find the nth term of AP: 1, 2, 3, 4, 5…., an, if the number of …

Solution Given nth term of a progression is (4n−10) i.e., T n =4n−10 First term, T 1 =4×1−10 =4−10=−6 =a Second term, T 2 =4×2−10 … WebSolution Verified by Toppr Correct option is A) Given, S n=4n 2−n When n=1 , S 1=4(1) 2−1=4−1=3 Now, obviously, the sum of the first term will be the first term itself, as there are no other terms involved. When n=2 , S 2=4(2) 2−1=16=2=14 The sum of the first 2 terms is equal to a 1+a 2 Therefore, a 1+a 2=14 We have shown, above, that a 1=3
