True or False: 5Σ { x | x is an even intger } ...*?

Answer 1

I notice that you used capitol sigma (which usually indicates a sum). This symbol looks a bit like E. Another symbol that looks like E is the "element of" symbol, which talks about things belonging to sets. If that's the one you meant to use, then your question is:

True of False: 5 belongs to the set of even integers.

Since 5 is odd (and odd numbers are not even), the answer is False.

Answer 2

This is not a complete statement so it cannot be true or false.
It looks like you have a premise but no conclusion.
I see a marks of ellipsis, that is, three dots, followed by an asterisk, which indicates that you meant to put in something else, perhaps a reference to a statement somewhere else. Try revising your question and then you can get a good answer.

Answer 3

"5Σ { x | x is an even intger }" is not a complete statement. So unless you left out something, it can't be true or false.

Answer 4

I assume you mean:
Is 5(2+4+6+8+10+12+....2n .....) even or odd?
If so then, we have:
5*2(1+2+3+4+5+6+ +n...)
=10(1+2+3+4+5+6+....+n)
which is even since 10 is even and ten times any number is even.

Answer 5

Your question does not make sense.
You have
five times the sum of { x such that x is an even integer}

This is not a statement. It can't be true or false.

Answer 6

question is incomplete
