Thank you for the opportunity to help you with your question!

When we represent a sequence by describing the relationship between its successive terms, we are representing the sequence recursively.

When we represent a sequence with a formula that lets us find any term
in the sequence without knowing any other terms, we are representing the
sequence explicitly.

Explicit rule

45, 50, 55, 60, 65 ..................Solution:_{}a_{n}
=a_{1}+d(n-1) where a1 is the firdt number and d id the common difference in this case a1=45 and d=5

Please let me know if you need any clarification. I'm always happy to answer your questions.
