We looked at finding the nth term rule, generating sequences from it and finding terms in a sequence from the nth term rule in part 1. Is 730 a term in the sequence 3n + 11? 730 isn’t the term, so we cannot substitute it in for n. We have to make the nth term rule equal to 730. 3n + 11 = 730, and then solve for 'n'. n = 239.7. Because n has come out as a decimal place, it means 730 is not in the sequence. Looking at another example: Is 265 a term in the sequence 4n + 5? Again, solve for n by solving this equation: 4n + 5 = 265. n = 65. Because 65 is a whole number it means that 265 is in the sequence. 265 is the 65th term in the sequence.

Not every triangle is a right-angle triangle, so we can't always use Pythagoras and SOHCAHTOA to find missing sides and missing angles. We instead use the sine rule or the cosine rule. They can both be used to find either missing sides or missing angles in any triangle (right angle or not). Click h
Our body is a pretty fantastic feat of engineering. But how does it work? How do all of the different components come together to keep us alive, keep us functioning and achieving our goals? In this video we are going to look at the levels of organisation in organisms, from smaller than cells to bigg
Human Defence Systems Against Pathogens | Health | Biology | FuseSchool Pathogens are disease causing microorganisms, that our body has many defence mechanisms against. The skin is the first physical barrier, providing a protective layer that is hard to penetrate. We also have sebaceous glands tha
