Hello,

Can anybody please help me to solve this problem

Every natural number n≥8 can be represented as n=3k+5ℓ, k,l are

natural numbers.

so, that true for n=8,9,10 - we can easily check it. Should I use

prove by induction? Then , how?

Or, is there's any other way?

Please, help!

Thank you in advance.
