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 … 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

WebThe nth term of an arithmetic sequence is given by : an=a1+(n−1)d an = a1 + (n−1)d. 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 ...
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 …
