In an ap sum of first m terms is n
WebThe 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. For example, in the progression, 16, 8, 0, −8, −16, ... the common difference is negative (d = 8 - 16 = 0 - 8 = -8 - 0 = -16 - (-8) =... = -8). 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 …
