An arrangement of numbers that follows a certain rule is called a
number sequence. Each number in a sequence is called a term.
1, 3, 5, 7, 9,
1st term 2nd term 3rd term 4th term 5th term
Completing a Number Sequence
Fill in the blanks to complete each number sequence. Then, write the
rules for each number sequence.
Number Sequence Rule
1, 2, 3, 1, 2, 3, 1, 2, , Numbers 1, 2, and 3 are
3, 5, 7, 9, 11, 13, 15, ,
1, 5, 3, 7, 1, 5, 3, 7, 1, , repeated.
1, , 7, 10, 13, 16, The numbers increase by 2.
1, 2, 4, 8, , 32, 64,
1, , 9, 27, 81, 243,
2, 3, 5, , 12, 17, 23,
1, 4, 9, 16, , 36, 49,
