What are the differences between arithmetic and geometric sequences? An arithmetic sequence has a constant difference between each term. For example: 2,4,6,8,10,12,… We can see clearly that all the …

The fact that we needed to take 2 turns to find the constant difference means we are dealing with a quadratic sequence. (3) Furthermore, because the difference is +4, we are dealing with a 2n 2 …

E-Z isomers (aka geometric or cis-trans isomers) and optical isomers are both examples of stereoisomers, two or more compounds with the same structural formula but with bonds that are …

Having learned a lot about the arithmetic and geometric sequences, most people are used to expressing the n th term of a sequence un in the form u n =u 1 +d (n-1) for the arithmetic sequence and u n =u 1 …

What is the difference between cells, tissues, organs and organ systems? You can think of these 4 things as a hierarchy, where each 'element' is a building block for the next level. The smallest 'unit' …

To do this, the first thing we do is calculate the difference between each term.7 - 3 =411 - 7 = 415 - 11 = 4The difference each time is 4. Therefore, the equation could be 4n. Let's try it out with the first term. …

So firstly, we need to work out the basic shape of the molecule which we can do by drawing the lewis structure (dot and cross diagram) and counting the number of ...

The first three terms of an arithmetic series are p, 5p – 8, and 3p + 8 respectively. (a) Show that p=4 (b) Find the value of the 50th term in the series.

Explain Hume's distinction between matters of fact and relations of ideas (5) David Hume, an empiricist, separated knowledge into categories - "matters of fact" and "relations of ideas". Hume argues that …

"et" is a coordinating word, to make a link between two words e.g. Je mange une pomme et une banane - I am eating an apple and a banane.
