What is the sum of first six terms of a sequence whose nth term is 8 - n?
nth term is 8 - n. an = 8 - n, so the sequence is {7, 6, 5, 4, 3, 2,...} (this is a decreasing sequence since the successor term is smaller than the nth term). So, the sum of first six terms of the sequence is 27.
What is the sequence for 0112358?
That's the famous Fibonacci sequence, where every term is the sum of the previous two.
What is the sum of the 3rd and 5th term in the sequence where the nth term is 3n-4?
16
What is the sum of the first 12 terms of the arithmetic sequence?
The sum of the first 12 terms of an arithmetic sequence is: sum = (n/2)(2a + (n - 1)d) = (12/2)(2a + (12 - 1)d) = 6(2a + 11d) = 12a + 66d where a is the first term and d is the common difference.
What is the sum of the arithmetic sequence?
The sum of an arithmetical sequence whose nth term is U(n) = a + (n-1)*d is S(n) = 1/2*n*[2a + (n-1)d] or 1/2*n(a + l) where l is the last term in the sequence.
The sum to three terms of geometric series is 9 and its sum to infinity is 8. What could you deduce about the common ratio. Why. Find the first term and common ratio?
The geometric sequence with three terms with a sum of nine and the sum to infinity of 8 is -9,-18, and 36. The first term is -9 and the common ratio is -2.
What if the second terms of an arithmetic sequence is 5 find the sum of 1st and 3rd term?
sequence 4 5 6 sum =10 sequecnce 0 5 10 sum=10
What is the sum of a 14-term arithmetic sequence where the last term is 30 and the common difference is -5?
875
What is the sum of the first 64 terms of the binary sequence?
A binary sequence is a sequence of [pseudo-]randomly generated binary digits. There is no definitive sum because the numbers are random. The sum could range from 0 to 64 with a mean sum of 32.
What is the general sum of an arithmetic sequence?
Given an arithmetic sequence whose first term is a, last term is l and common difference is d is:The series of partial sums, Sn, is given bySn = 1/2*n*(a + l) = 1/2*n*[2a + (n-1)*d]
The first term of a sequence is x and each term after the first term is equal to 5 less then 4 times the previous term What is the average of the second and third terms?
The 1st term is (X). The 2nd term is (4X-5). The 3rd term is (16X-25). The average of the 2nd and 3rd terms is 1/2 of their sum. Their sum is (4X-5) + (16X-25) = (20X-30). Their average is (10X-15).
