Question

what is the relation among Sn , Sn-1 and Tn for one mark​

Answer 1

Answer:

The sum of the first n terms of a series is given by Sn = 4n2 + 5. Find an expression for the n-th term, Tn. One method is to use the relationship: Sn−1 + Tn = Sn ⇒ Tn = Sn − Sn−1 (1) Another method is to obtain the first few terms of the series directly.
