## Finding the Nth Term

Term:-   0    1     2      3      4      5

3,    7,     11,   15,   19

Write an expression in terms of n for the above number sequence.

• Find the number rule                                                                    +4
• Find the zero (0) term for the above sequence                        -1
• Write the nth term                                                                   4n - 1
• Check it  4n - 1        4 x1(1st term)  -1  =  3    which is the 1st term

Answer:-          4n - 1

rule +4       zero term  -1

## Finding the Nth Term

Term:-    0      1      2       3      4      5

30,    24,   18,    12,    6

Write an expression in terms of n for the above number sequence.

• Find the number rule                                                                    -6
• Find the zero (0) term for the above sequence                        36
• Write the nth term                                                                   -6n + 36
