In this video we are going to look at how we work out whether a number is in sequence or not. 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.

What does diabetes mean to you? Something to do with sugar right? Would you be shocked if I told you that every 6 seconds someone dies from diabetes?
One in 11 adults worldwide has diabetes, with 1 in 2 not being diagnosed. So it is important that we all know what it is, how it can be detected and

An acid is a substance that will dissociate in water to give a proton (or H+ ion) and a conjugate base. An acid is considered to be strong if dissociation nears 100%, and weak if dissociation is usually less than 1%.
In this lesson, we will learn about strong alkalis and weak alkalis.
An alkali

In this video, we will focus on Urban ecology, which is the study of ecology where humans are abundant and have made significant changes to the local environment, such as cities.
