3. OBJECTIVE
To be able to find the
terms of a sequence.

4. Formulae from Sequences
If we know the formula for a sequence, we can find the
first 5 terms of the sequence.
For example: 2n
‘n’ represents the term’s number. 1 2 3 4 5
Term (n) 2 4 6 8 10
Value

5. Formulae from Sequences
Find the first 5 terms of the sequence.
3n + 5
‘n’ represents the term’s number. 1 2 3 4 5
Term (n) 8 11 14 17 20
Value

6. Formulae from Sequences
Find the first 5 terms of the sequence.
10n - 10
‘n’ represents the term’s number. 1 2 3 4 5
Term (n) 10 20 30 40
Value

7. Formulae from Sequences
Find the first 5 terms of the sequence.
100 – 10n
‘n’ represents the term’s number. 1 2 3 4 5
Term (n) 90 80 70 60 50
Value
