In his Imperium Naturae<span>, Linnaeus established three kingdoms, namely </span>Regnum Animale<span>, </span>Regnum Vegetabile<span> and </span>Regnum Lapideum<span>. This approach, the Animal, Vegetable and Mineral Kingdoms, survives today in the popular mind, notably in the form of the parlour game question: "Is it </span>animal, vegetable or mineral<span>?". The work of Linnaeus had a huge impact on science; it was indispensable as a foundation for </span>biological nomenclature<span>, now regulated by the </span>nomenclature codes<span>.</span><span>
But the system is based solely on physical characteristics, due to not having the proper technology to investigate the molecular data of animals</span>
Hey there! I’m happy to help!
We want to look for the twentieth term in this sequence. Because it is arithmetic, this means that the same term will always be added or subtracted.
As we can see, our first term is 36 and then the third is twenty eight. This is a difference of eight, and since our subtracted term will always be the same, we will take this eight and divide it by two, so we can now see that we are subtracting four for each term.
To find the twentieth term, you could count, but that would be a hassle. You can also use the arithmetic sequence formula, which I will show below.
You take the desired term (20)
Subtract 1 (19)
Multiply it by the common term/difference (19*-4=-76)
And then add the first number of the sequence (-76+36= -40)
You can now do those exact same steps for any arithmetic sequence you are dealing with!
So, your twentieth term is -40!
I hope that this helps!
34 divided by 4 is 8.5 minutes in all 4 activities.
