WebNov 27, 2024 · Geometric Sequence Recursive Formula. In a geometric sequence, Every next number after the first number is the multiplication of the previous number with a fixed, non-zero number. Geometric sequences Written like this. an = a × rn-1 – where a refers to the nth term in the sequence. i.e. a, ar, ar2, ar3, … WebIt sounds like you have a geometric sequence which uses multiplication or division to get to the next item in the sequence. ... =15-3n as follows: a(n)=15-3(n-1)-3 ==> a(n)=12-3(n-1). As you can see, this final conversion is the standard explicit equation. so a(1)=12 and common difference = -3. Hope this helps someone! Comment Button navigates ...

WebSep 16, 2024 · Explicit Formula for a Geometric Sequence. A geometric sequence is one where the ratio between any two consecutive terms is constant. We will denote such number by {eq}q {/eq} (in reference to the ... WebA geometric sequence is a sequence in which the ratio of any term to the previous term is constant. 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.
