Adele’s new album ’30’ has been universally praised by critics and fans but it’s the numbers that have mathematicians excited – so much so that they’ve created an ‘Adele sequence’
Adele has recently blown us all away with new album, ‘30’, making this the fourth studio album of her career.
Critics are loving it and Adele is receiving plenty of praise from fans and music buffs alike, but what about the numbers?
It’s easy to identify a common theme with all of Adele’s albums, as they reflect the age when she wrote them.
There was 19, 21, 25 and now 30, which left many mathematicians scratching their heads, trying to identify a sequence.
Mathematicians love sequences, which is why professor of mathematics Anthony Bonato wanted to explore the patterns in music further.
In his blog, he said: “The chronological list of Adele’s album titles 19, 21, 25 and 30 was coined the ‘Adele sequence’ by David Patrick, senior math and science curriculum director at the Art of Problem Solving.
“Mathematicians love sequences, and they pop up all over the field. Sequences are simply numbers listed in a given order.
“The simplest sequence we learn about as children are the counting numbers 1, 2, 3, 4 and so on.”
In the article by David Patrick, he insists that the choice of numbers for Adele’s albums are examples of an ‘integer sequence.’
The general definition of an integer sequence is an ordered list of integers, which are basically whole numbers.
An example of a famous integer sequence is the Fibonacci sequence, a sequence starting with 0 and 1, and then adding any two consecutive numbers.
Patrick even came up with his very own ‘Adele sequence’ and searched the ‘ OEIS ’ which is an online database for integers, to find a link.
He uncovered the sequence with the title ‘A072666’, whose first few numbers are: 2, 3, 4, 5, 6, 8, 10, 11, 13, 14, 18, 19, 21, 25, 30, 31, 36, 41, 43 and 44.
The famous Adele sequence is there in the middle, 19, 21, 25, 30, which suggests that her next album will be 31.
It’s not just Adele that is drawn to using numbers in her titles, The Beatles, Spice Girls, and David Bowie are just a few artists who dabble with numerical titles.
You’ve got The Beatles ‘Eight Days a Week’ and ‘When I’m Sixty Four’ or “7/11” by Beyoncé, not to mention Ed Sheeran’s mathematically titled albums using symbols.
So, Adele may not know what her next album is going to be called, but if it were down to maths, it would be 31.
