Arithmetic Sequences and the Explicit Formula with Recursive
How to write an #explicit formula for an #arithmetic #sequence:
a(n) = a(1) + d(n - 1)
a(1) is the value of the first term
n is the term number that you are looking for
a(n) is the value of the nth term
d is the common difference (the amount you are adding or subtracting)
To find the 11th term, replace the "n" with 11 and evaluate (do order of operations) to find the value.
This video could work for #Algebra students who were absent, or in a flipped classroom.
