What is the 4th term of the geometric sequence 5/20 80?
4th term will be 40 + 25 = 65.
What type of sequence is 5/20 80?
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 4 gives the next term. In other words, an=a1⋅rn−1 a n = a 1 ⋅ r n – 1 . This is the form of a geometric sequence.

What type of sequence is 6 9 12?
This is an arithmetic sequence since there is a common difference between each term.
Is 5/20 80320 is a geometric?
Precalculus Examples This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 4 gives the next term.
Is a geometric sequence linear?
Arithmetic sequences are linear functions. Geometric sequences are exponential functions. While the n-value increases by a constant value of one, the f (n) value increases by multiples of r, the common ratio.
How do you find the next term in a geometric sequence?
5 5, 20 20, 80 80, 320 320 This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 4 4 gives the next term. In other words, an = a1 ⋅rn−1 a n = a 1 ⋅ r n – 1.
What are the properties of geometric sequence?
Geometric sequence properties. A geometric sequence is an ordered set of numbers, in which each consecutive number is found by multiplying the previous term by a factor called the common ratio. Just as in case of any other sequence, it can have a finite (for example 30) or an infinite number of terms.
Which formula to find the nth term in geometric progression?
the formula to find the nth term in Geometric Progression is an = a1 ⋅ rn−1 Use now a1 = 5 and r = −2 and n = 15 in the formula an = a1 ⋅ rn−1
How do you find the sum of a geometric series?
In mathematics, geometric series and geometric sequences are typically denoted just by their general term aₙ, so the geometric series formula would look like this: S = ∑ aₙ = a₁ + a₂ + a₃ +… + aₘ Where m is the total number of terms we want to sum.
