Question

Was wondering, I think this statement (in the comments) is true.
I think it is, and I am pretty sure.
Confrim please....

Answer 1

\[\LARGE c_{_1} \times \sum_{n=c_{_2}}^{c_{_3}}f(n)= \sum_{n=c_{_2}}^{c_{_3}} c_{_1} \times f(n)\]
(where \[\large c_{_1}~,~ c_{_2}~,~ c_{_3},\] are just 3 numbers that can be, but not necessarily equal to each other)

and assuming that
\[ \large c_{_1}\ne 0,~~1\]

Answer 2

\[\large {\rm and} {~~c_{_3}} {\rm~~is~~a~~nat ural~~number. }\]
