Activity: number patterns (terms) [lo 2.1, lo 2.3.1, lo 2.3.2]

9. did you know?

The numbers in a number sequence are also known as TERMS .

10. problem

Make your own number sequence!

With a friend, work through the following example:

  • Draw a flow chart with two operator blocks:
  • Fill the answers in on the right.

N- values

Your number sequence is 7 ; 12 ; 17 ; 22 ; 27

Your rule will be:

T n = (5 × n ) + 2

Term which

one = 5 n + 2

Thus: T 2 = (5 × 2) + 2 = 12

T 12 = (5 × 12) + 2 = 62

  • If you are certain that you understand the above, compile your own number sequence.

Do you understand the preceding work?

  • Complete the following by placing a tick in the appropriate block:
uncertain reason­ably certain very certain
  • I can see various patterns in numbers
  • I am able to predict what the subsequent pattern will be
  • I can explain the Fibonacci series and complete the next sequence
  • I am able to draw the Fibonacci spiral
  • I can explain the Pascal triangle to a friend
  • I can determine triangular numbers by means of a formula
  • I can determine the sum of numbers by using the Gauss method
  • I am able to compile my own number sequences

Assessment

Learning Outcome 2: The learner will be able to recognise, describe and represent patterns and relationships, as well as to solve problems using algebraic language and skills.

Assessment Standard 2.1: We know this when the learner investigates and extends numeric and geometric patterns looking for a relationship or rules, including patterns.

Assessment Standard 2.3: We know this when the learner represents and uses relationships between variables in order to determine input and/or output values in a variety of ways using;

2.3.1: verbal descriptions;

2.3.2: flow diagrams.

Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
