Write the first five terms of the sequence.

a n = -1() n - 1

+1,- 1, +1, -1, +1

Step-by-step explanation:

Given sequence : =

where represents the term of the sequence.

⇒The first term is obtained by substituting n=1, the second term is obtained by substituting n=2 and so on...

= = = +1

= = = -1

= = = +1

= = = -1

= = = +1
