A time-series is a vector used to describe a process evolving as a function of time. Suppose c₁ € R³65 and C₂ € 365 contains the number of cases of a virus over 365 consecutive days. Provide interpretations of the following mathematical statements (1 sentence per response). Interpretations should be in terms of virus cases, and not a re-statement of the mathematical expression. (a) (C₁)k+1 > (C₁)k for k = 1,2, ..., 364. (b) cfc₂=0 (c) ||c₁||1 >||C₂||1, where || ||1 denotes the 1-norm.

Question
A time-series is a vector used to describe a process evolving as a function of time. Suppose c₁ € R³65 and
C₂ € R³65 contains the number of cases of a virus over 365 consecutive days. Provide interpretations of the
following mathematical statements (1 sentence per response). Interpretations should be in terms of virus
cases, and not a re-statement of the mathematical expression.
(a) (C₁)k+1 > (C₁)k for k = 1, 2, ..., 364.
(b) c ₂ = 0
(c) ||c₁||1 > ||C₂||1, where || ||1 denotes the 1-norm.
