Unit 5 Patterns & Algebra 20 January 2021 Class 37 Keywords Linear / Arithmetic Sequence Term Common Difference Term to Term Rule General Term Constant Varies 1
Do you notice anything about the following sequences and general terms? 2, 4, 6, 8 . 4, 7, 10, 13 . 1, 5, 9 , 13 . ??= 2? + 3 5, 7 , 9 , 11, 13 . Hint! Check the common difference .
Can you draw Ted on his 4th Birthday? 21 How many matchsticks would be needed?
How many matchsticks will you need to make Ted on his 6th Birthday? 29 Is there a way to figure this out without drawing him?
How many matchsticks will you need to make Ted on his 6th Birthday? 29 We needed 21 matchsticks to make Ted on his 4th Birthday. Each year we add 4 matchsticks. This is the term to term rule 21, 25, 29 Also known as the Common Difference of this linear sequence
The number of matchsticks needed to make Ted represents a Linear Sequence Can you find the first three terms of this sequence? Can you find figure out the next two terms?
The number of matchsticks needed to make Ted represents a Linear Sequence 9 , 13, 17, 21, 25, How do we know that this is a Linear Sequence?
Ted represents a linear sequence 9 , 13, 17, 21, 25, COMMON DIFFERENCE
How many matchsticks will you need to make Ted on his 6th Birthday? 29 Did anyone have any other methods to get to this answer?
What do you think Ted looked like when he was born? Born
What part of Ted remains constant as he gets older? What part of Ted varies as he gets older? How does it vary? Born
We can make a General Term for the number of matchsticks needed to make Ted.. ??= 4? + 5
We can make a General Term for the number of matchsticks needed to make Ted.. Common Difference = 4 ??= ?? + 5 Constant Varies
