In previous blogs, we’ve looked at some interesting integer sequences. We’ve looked at the Fibonacci sequence, the Look-and-say sequence, Golomb’s sequence and Van Eck’s sequence. Today, we’re looking at the Lazy Caterer’s sequence.You can find this sequence on the Online Encyclopedia of Integer Sequences here. How to generate the sequence… Continue reading The Lazy Caterer’s Sequence
In previous blogs, we’ve looked at some interesting integer sequences. We started with the Fibonacci sequence, then the “Look-and-say” sequence and most recently Golomb’s sequence. Today, it’s Van Eck’s sequence.The sequence was first published to the Online Encyclopedia of Integer Sequences (OEIS) in 2010 by a hobby mathematician called Jan… Continue reading Van Eck’s Sequence
In a previous blog I looked in more detail into “the daddy of all integer sequences” - the Fibonacci sequence. While the Fibonacci sequence is an impossible sequence to match up to, there are plenty of other intriguing integer sequences out there. So if you can deal with the disappointment… Continue reading The Look-and-Say Sequence
In our blog we’ve already covered Kaprekar’s constant, as well as the (not-so) magic number 10. Here’s another cool little trick to sink your teeth into…First, pick a positive integer (whole number).Now, we are going to generate a sequence of numbers, starting with our starting number. Each term in the… Continue reading Hailstone Numbers
Following on from our previous blogs on identifying different types of sequences and finding the nth term of a linear sequence, in this blog I will show you how to find the nth term of a quadratic sequence. It is important to note that this topic is only examinable on… Continue reading How to find the nth term of a quadratic sequence
