Example 1 1 2 1 2 1 3 1 3 1 4 1 n 1 n 1 clearly the nth partial sum of this series is 1 1 n 1 and so the series converges to 1.
Sequence and series pdf engineering mathematics. So the first ten terms of the. 1 sequences and series the intuitive concept of sequences of numbers involves not only a set of numbers but also an order in which these numbers have been placed. The terms of a geometric series form a geometric progression meaning that the ratio of successive terms in the series is constant. A series is said to telescope if almost all the terms in the partial sums cancel except for a few at the beginning and at the ending.
