Answer:

Explanation:

To prove: The sum of two consecutive exponents of the number 6 is divisible by 7.

Proof: Let the consecutive exponents of the number 6 be:


6^(n) and
6^(n+1).

Then , the sum of two consecutive exponents of the number 6 is represented as :


6^(n)+6^(n+1).

Now, according to question, we have to prove that The sum of two consecutive exponents of the number 6 is divisible by 7, thus


6^(n)+6^(n+1) =6^(n)+6^(n){*}6

=
6^(n)(1+6)


6^(n)+6^(n+1)=
6^(n)(7)

which means that the sum of two consecutive exponents of the number 6 is divisible by 7.

Hence proved.
