Write the first five terms of each of the sequences in Exercises 11 to 13 and obtain the corresponding series: a1 = a2 = 2, an = an - 1 - 1, n > 2
Solution:
The sequence is a list of numbers (or items) that exhibits a particular pattern.
a1 = a2 = 2, an = an - 1 - 1, n > 2
⇒ a3 = a2 - 1 = 2 - 1 = 1
a4 = a3 - 1 = 1 - 1 = 0
a5 = a4 - 1 = 0 - 1 = - 1
Hence, the first five terms of the sequence are 2, 2, 1, 0 and - 1
The corresponding series is 2 + 2 + 1 + 0 + (- 1) + ....
