Here we answer many questions about the sequence 49, 98, 196, 392... What type of sequence is 49, 98, 196, 392? What is the next number in the sequence 49, 98, 196, 392? What is the nth number in the sequence 49, 98, 196, 392? What is the sum of the first 10 terms in the sequence 49, 98, 196, 392? What is the sum of the first n numbers in the sequence 49, 98, 196, 392?
In addition, we will also give you the formula that is used to calculate the next number or the nth number in 49, 98, 196, 392, and the formula to calculate the sum of n numbers in 49, 98, 196, 392.
A sequence is a list of numbers in a pattern, and each number in the sequence is called a term. We will use "terms" and "numbers" interchangeably on this page.
So, what type of sequence is 49, 98, 196, 392? The sequence 49, 98, 196, 392 has a common ratio of 2 between each term. We call this kind of sequence a geometric sequence. Below is an image illustrating the correlation between the geometric sequence 49, 98, 196, 392 and its common ratio of 2.
Now, what is the next number in the sequence 49, 98, 196, 392? Below is the formula used to calculate the next number in a geometric sequence, such as 49, 98, 196, 392. The first term listed in the sequence is "a", the common ratio is "r", and "n" is the nth term of the geometric sequence.
a × r^(n-1) = Next Term
As stated above, the common ratio (r) between each term is 2. Furthermore, the next term in 49, 98, 196, 392 is the fifth term (5), and the first term is 49. When we enter these values into our formula, we get the following answer:
49 × 2^(5-1) = 784
Thus, the next number (term) in the sequence 49, 98, 196, 392 is 784. The tool below calculates the nth term of the sequence using the formula above. For example, type in 20 if you want the 20th term in the sequence 49, 98, 196, 392, or 100 if you want the 100th term in the sequence 49, 98, 196, 392.
Let's move on to our next question. What is the sum of the first 10 terms in the sequence 49, 98, 196, 392? We use the formula below to calculate the sum of the first n terms in a geometric sequence such as 49, 98, 196, 392. Again, note that the first term is "a", the common ratio is "r", and "n" is the nth term of the geometric sequence.
(a × (1 - r^n)) ÷ (1 - r) = Sum
When we enter the a, r, and n values into our formula, where n is equal to 10, we can calculate the sum of all numbers up through the 10th term in the sequence 49, 98, 196, 392, as seen below:
(49 × (1 - 2^10)) ÷ (1 - 2) = 50127
Therefore, the sum of all numbers up through the 10th term in the sequence 49, 98, 196, 392 is 50127. Below is another tool we created to make these calculations easier for you. This tool can calculate the sum of any number of terms in the sequence 49, 98, 196, 392 using the formula mentioned above. For example, if you type in 15, then it will calculate the sum of the first 15 terms in the sequence 49, 98, 196, 392.
