Use math notation to describe the following sequence: <br> 1, -1, 1, -1,...
Veseljchak [2.6K]

Answer:

The math notation to the given sequence is  a_n=(-1)^{n+1} for n=1,2,3,... is verified and it is true

Step-by-step explanation:

Given sequence is 1,-1,1,-1,...

Let a_1=-1,a_2=1,a_3=-1,a_4=-1,...

To find the math notation for the given sequence :

a_n=(-1)^{n+1} for n=1,2,3,... verify that it is true or not

Put n=1 in the above equation we get

a_1=(-1)^{1+1}

=(-1)^2

Therefore a_1=1

Put n=2 in the a_n=(-1)^{n+1} equation we get

a_2=(-1)^{2+1}

=(-1)^3

Therefore a_2=-1

Put n=3 in the a_n=(-1)^{n+1} equation we get

a_3=(-1)^{3+1}

=(-1)^4

Therefore a_3=1

and so on

Therefore the math notation to the given sequence is  a_n=(-1)^{n+1} for n=1,2,3,... is verified and it is true
