Arithmetic sequence problem. nth term of an arithmetic progression (basic) nth term of an arithmetic progression (intermediate) nth term of an arithmetic progression (advanced) nth term challenge problems. Math > Class 10 math (India) > WebThe n th term of an AP can be obtained by a n = a + (n − 1)d The sum of an AP can be obtained by s n = n/2 [2a + (n − 1) d] The graph of an AP is a straight line with the slope as the common difference. The common difference doesn't need to be positive always.

WebAn arithmetic progression or arithmetic sequence (AP) is a sequence of numbers such that the difference from any succeeding term to its preceding term remains constant throughout the sequence. The constant difference is called common difference of that arithmetic progression. For instance, the sequence 5, 7, 9, 11, 13, 15, . . . is an arithmetic progression … Webn th term of an AP is T n =a+ (n−1)d For an AP with the first term as 'a' and common difference as 'd', the seventh term is a + 6d. According to the question, the common difference (d) is −4 and the seventh term (a 7) is 4. So, a + 6d will be ⇒ a + 6 (−4) = 4 ⇒ a = 28 Hence, the first term is 28. Concept: nth Term of an AP
WebSolution: An arithmetic progression (AP) is a sequence where the two consecutive terms have the same common difference. It is obtained by adding the same fixed number to its … WebIn an AP, if the common difference (d) = -4 and the seventh term (a 7) is 4, then find the the first term. Hard Solution Verified by Toppr we know, a n=a+(n−1)d so, a 7=a+(7−1)d or, …
WebNov 25, 2024 · Given d = – 4 and a 7 = 4. We know that nth term of A.P. is. a n = a + (n – 1)d. a 7 = a + (7 – 1)d [n = 7] 4 = a + 6(– 4) ∴ a = 4 + 24 = 28 . ...

To find the nth term, first calculate the common difference, d. Next multiply each term number of the sequence (n = 1, 2, 3, …) by the common difference. Then add or subtract a number from the new sequence to achieve a copy of the sequence given in the ...
WebJan 26, 2024 · nth term of an AP: According to a definite rule, some numbers are arranged in a definite order to form a sequence.The number occurring at the \({n^{th}}\) place is called the nth term of an AP, denoted by \({T_n}\) or \({a_n}\). A sequence in which each term differs from its preceding term by a constant is called an arithmetic progression, written …
