What is the next number in the sequence 1/3 9?
It could be 1*3=3, 3*3=9 which would mean the next number in the sequence would be 9*3= 27, which would mean the second number in the sequence would be 81 because 27*3=81 but you could also look at it like this 1+2=3, 3+6=9 which could be 27 if you look at it as 2, for the first then 2*3=6 which would mean that it …
What kind of sequence is 1/3 9?
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 −3 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 is the sum of the geometric sequence 1 3 9 if there are 14 terms?
2391484
Summary: The sum of the geometric sequence 1, 3, 9, if there are 14 terms is 2391484.
What is the sum of the geometric sequence 1?
To find the sum of a finite geometric series, use the formula, Sn=a1(1−rn)1−r,r≠1 , where n is the number of terms, a1 is the first term and r is the common ratio .
What number should come next in this series 1 4 9 16?
What number should come next in this series 1 4 9 16? The series appears to increase as follows: 1 (+3), 4 (+5), 9 (+7), 16,, etc. If so, the next number in the series would be 25 (16 + 9). While mathematically equivalent, a simpler description is:
What is the next number in the sequence 1 2 3 4?
Step by step solution of the sequence is Series are based on square of a number 1 = 12, 4 = 22, 9 = 32, 16 = 42, 25 = 52 ∴ The next number for given series 1, 2, 3, 4, 5 is 6 ∴ Next possible number is 62 = 36
How do you find the next number in a series?
Here the rule is 2x+3. You must double each number and then add three to find the next number. Advanced Series. Advanced series are creative and somewhat unpredictable. They might use exponents or other mathematical functions. They might also be dynamic. Take the Fibonacci sequence, for example.
What is the formula for series in math?
Series Formulas. 1. Arithmetic and Geometric Series. Definitions: First term: a 1 Nth term: a n Number of terms in the series: n Sum of the first n terms: S n Difference between successive terms: d Common ratio: q Sum to infinity: S. Arithmetic Series Formulas: a a n dn = + −1 ( 1) 1 1.
