300

Subtract 75 from each term

What is the missing term in the pattern?

450,375,___, 225

61

Double each term and minus 1

What is the missing term in the pattern?

 5,9,17,31,___

What is the pattern rule?

0.222, 0.333, 0.444, 0.555

81 is the 4th term

 (See below)

3, 9,27, 81

The pattern rule is

 divide each term by ten.

7 000 000, 700 000, 70 000, 7 000, 700, 70, 7.

The pattern rule is

 mulitply each term by 10.

What is the pattern rule?

0.045, 0.45, 4.5, 45, 450.

The pattern rule is

 divide each term by 100.

What is the patten rule?

891 000, 8 910, 89.1, 0.891

 Solve for the missing variable (n): 

7.4 x n = 74

 Solve for the missing variable (n): 

0.05 x n = 50

 Solve for the missing variable (n): 

7.4 divided by n = 0.074

If n + 1 = 15 and

n +  1 + s = 19

then what value does s represent?

If a + 2 = 18 and

a +  2 + s = 29

then what value does s represent?

If t - 1 = 10 and

t -  1 + s = 19

then what value does s represent?
