Use math notation to describe the following sequence:
1, -1, 1, -

The math notation to the given sequence is  for n=1,2,3,... is verified and it is true

Step-by-step explanation:

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

Let

To find the math notation for the given sequence :

for n=1,2,3,... verify that it is true or not

Put n=1 in the above equation we get

Therefore

Put n=2 in the equation we get

Therefore

Put n=3 in the equation we get

Therefore

and so on

Therefore the math notation to the given sequence is   for n=1,2,3,... is verified and it is true

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
