Answer:The first differences are 6,8,10,12,14. The second difference is 2. Therefore half of 2 is 1 so the first term is n^2. Subtract this from the sequence gives 5,8,11,14,17. The nth term of this sequence is 3n + 2. So the final formula for this sequence is n^2 + 3n...

Write an expression for the apparent nth term (an) of the sequence. 1,6,11,16,21,⋯ Arithmetic Sequence: If we notice that the succeeding terms in a sequence are produced by adding a constant value to every preceding value, then the sequence is an arithmetic...
Let's understand this formula in action with an example. Consider the arithmetic sequence 2, 5, 8, 11, 14. To find the 6th term of this sequence using Newton's Little Formula, we first need to identify the values of a and d. In this case, the first term a is 2, and the common...
What is the sum of a finite arithmetic sequence from n = 1 to n = 10, using the the expression 3n - 8 for the nth term of the sequence? Arithmetic Sequences- The Terms and, The Sum of Its Terms: The arithmetic sequences ...
Arithmetic Progression (AP) is a sequence of numbers in order that the common difference of any two successive numbers is a constant value. Learn with arithmetic sequence formulas and solved examples.
I was wondering about how can one find the nth term of fibonacci sequence for a very large value of n say, 1000000. Using the grade-school recurrence equation fib(n)=fib(n-1)+fib(n-2), it takes 2-3 min to find the 50th term!
