Sequences and Series

Sequences: A sequence is a set of terms in a definite order with a rule for obtaining the terms. e.g. 1, 1/2, 1/3 ,……., 1/n,…….. is a sequence. Arithmetic Progression (AP): AP is a sequence whose terms increase or decrease by a fixed number. This fixed number is called the common difference. If a is the first term & d the common difference, then AP can be written as a, a + d,…
