A generating function for an arbitrary sequence an is the infinite sum Σnanxn. In the specific case of the Fibonacci numbers, that means ΣnFib(n)xn. In words, it's an infinite power series, with the coefficient of xn being the nth Fibonacci number. Now, Fib(n+2)=Fib(n+1)+Fib(...
Solution 2: IF and SEQUENCE =ArrayFormula(FLATTEN(IF(SEQUENCE(25),{1,299,13,50}))) In this formula, SEQUENCE generates a column of 25 numbers. An IF formula wrapper then takes each number as an input and, since numbers are truthy values, the IF outputs the array. The FLATTEN functio...

numbers of the sequence occur throughout nature, such as in the spirals of sunflower heads and snail shells. The ratios between successive terms of the sequence tend to thegolden ratioφ = (1 +√5)/2 or 1.6180…. For information on the interesting properties and uses of the Fibonacci ...
Change the score from “Above 550” to single numbers “550” (in Column E below), as VLOOKUP identifies a sequence of numbers as a table_array. Always sort the data in the table in ascending order to avoid errors. Solution: Step 1:Select “Cell C2” and enter the formula “=VLOOKUP...
The formula that defines the Fibonacci sequence is: Fn=Fn-1+Fn-2 We can also describe this by stating that any number in the Fibonacci sequence is the sum of the previous two numbers. For the most common representation of the Fibonacci sequence, the first two terms are defined asF0=0, ...

What is an arithmetic sequence? An arithmetic sequence is a sequence of numbers with a definite pattern. In an arithmetic sequence, the difference between any two consecutive numbers is always a constant value. Sometimes the arithmetic sequence is also named arithmetic progression. An arithmetic seque...
