can you explain how to use a sequence like how to plug in numbers to the sequence
is the formula
Its like a is 0 so n=n
The formula a_n=n says that "a" which is a term, n identify which term it is, so first term we would write it as a_1 = As the sequence says
here we see that a_1=1 and so on for a_15=15
so we can make a general formula (Explicit) which is a_n=n for n is any number.
