Qld General Maths Unit 3 Revision of Terms and Units

What does t_n represent?

• The n^th time in a sequence

• The n^th term in a sequence

• The net term

• A number in a sequence

 $n^{th}$  represents what?

• Where in a sequence a number is located

• An abstract thought

• A number in the equation

• A number

 $t_1$  represents:

• The first time

• The number 1

• The first term in a sequence

• A sequence with 1 term

 $n$  represents:

• Numbers

• Now

• The term number

• Nine

 $d$  represents:

• details

• common difference

• divide

• down

What is 

 $t_{n+1}$ ?

• The term occurring after the  $n^{th}$  term

• Term  $t_n$  plus one more

• A number

• Not sure

What is a sequence?

• A series of terms connected by a defined relationship

• A range of motions carried out in a particular way

• Step-by-step instructions

• Connected numbers

Define an arithmetic sequence.

• A sequence of numbers such that the difference between any two successive members of the sequence is constant.

• A set of numbers that have a defined relationship

• Adding numbers together to make a sequence

• A rule to make a series of numbers

Define recursion

• A repeating pattern

• From a given starting point, a sequence is built by moving from one term to another by applying the same rule

• A not-excursion

• Using addition to create a growing sequence from a given point, to build a series of terms that are connected by a relationship

In a sequence,

 $a$  is the... 

(identify the most correct answer)

• starting point

• first term

• number of terms

• gap between numbers
