Answer:
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
