What is a counterexample to the conditional statement?
posledela

Answer:

The number 9 is greater than 1 and less than 10, while its factors are 1, 3 and 9, therefore it is a counter example to the statement.

Step-by-step explanation:

There are four odd numbers between 1 and 10, they are: 3, 5, 7 and 9. Let's check the factors for each of them.

For 3:

\frac{3}{1} = 3\\\frac{3}{3} = 1

Therefore 3 is not a counter example to the statement, because it behaves as stated.

For 5:

\frac{5}{1} = 5\\\frac{5}{5} = 1

Therefore 5 is not a counter example to the statement, because it behaves as stated.

For 7:

\frac{7}{1} = 7\\\frac{7}{7} = 1

Therefore 7 is not a counter example to the statement, because it behaves as stated.

For 9:

\frac{9}{1} = 9\\\frac{9}{3} = 3\\\frac{9}{9} = 1\\

Therefore 9 is a counter example to the statement, since it can be divided by 1, 3 and 9.

What are the first five terms of a= 2 × n<br>​
kenny6666 [7]

Answer:

<em>2,4,6,8,10</em>

Step-by-step explanation:

To find the first 5 terms we can substitute numbers for "n"

We can create a table:

x              y

1              2

2             4

3             6

4             8

5            10

To get the values we just plug in numbers:

a(1)=2(n)

a(1)=2(1)

a(1)=2

a(2)=2(2)

a(2)=4

...... etc.
