How does the explicit formula work?

This formula allows us to simply plug in the number of the term we are interested in, and we will get the value of that term. In order to find the fifth term, for example, we need to plug n = 5 n=5 n=5 into the explicit formula.

Now what we have is we have a what they call an explicit formula meaning that it'll take youMoreSo. Now what we have is we have a what they call an explicit formula meaning that it'll take you right to any particular term. So let's write this in a little bit more general way a sub n equals a sub

What is an explicit formula for geometric?

The explicit formula for a geometric sequence is of the form an = a1r-1, where r is the common ratio. A geometric sequence can be defined recursively by the formulas a1 = c, an+1 = ran, where c is a constant and r is the common ratio.

What is the explicit rule for the arithmetic sequence an n 1?

The explicit formula for the nth term of an arithmetic sequence is an = a1 + d(n – 1), where an is the nth term of the sequence, a1 is the first term of the sequence, and d is the common difference of the sequence.

How do you write a sequence in explicit form?

How To: Given an explicit formula, write the first n terms of a sequence.

  1. Substitute each value of n into the formula. Begin with n=1 to find the first term, a1 .
  2. To find the second term, a2 , use n=2 .
  3. Continue in the same manner until you have identified all n terms.
