Geometric sequence how to find common ratio
WebThe terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. For instance, if the first term of a geometric sequence is a1 = −2 a 1 = − 2 and the common ratio is r= 4 r = 4, we can find subsequent terms by multiplying −2⋅4 − 2 ⋅ 4 to get −8 − 8 then multiplying ... WebYou're right, that sequence is neither arithmetic nor geometric. That sequence is the "factorial" numbers. As you have noticed, it has a recursive definition: a₁ = 1, and aₙ = n· aₙ₋₁ Factorials crop up quite a lot in mathematics. They even have a nifty bit of notation - the exclamation mark. Factorial(n) = n! See here for a video:
