1,    3,    9,    27,    ____ ,    243<\/p>\n<\/div><\/div>\n\n\n\n

First, look for a pattern. Notice how each number is 3 times the previous number:<\/p>\n\n\n\n

1, 3, 9, 27, __, 243<\/p>\n\n\n\n

Multiply 27 by 3 to find the missing number:<\/p>\n\n\n\n

27 \u00d7 3 = 81<\/p>\n\n\n\n

To make the pattern complete, the number 81 must go in the blank space.<\/p>\n<\/div><\/div>\n\n\n\n

1, 4, ___ , 16, 25, 36, 49, 64<\/p>\n<\/div><\/div>\n\n\n\n

Look for the pattern. 1, 4, 16, 25, 36, 49 and 64 are all <\/p>\n\n\n\n

perfect squares.Rule:<\/strong> The nth<\/sup> term is n2<\/sup>.<\/p>\n\n\n\n

You are trying to find the 3rd<\/sup> term. Plug n=3 into the rule.<\/p>\n\n\n\n

n2<\/sup> = 32 <\/sup>= 9<\/p>\n\n\n\n

The missing number in the pattern is 9.<\/p>\n\n\n\n

The pattern is:<\/p>\n\n\n\n

3,    5,    8,   _______ ,    17,    23,    30<\/p>\n<\/div><\/div>\n\n\n\n

Find the pattern. Look at how much you add to each number to get the next number:<\/p>\n\n\n

\n
\"\"<\/figure><\/div>\n\n\n

The amount you add increases by 1 each time. Now you know how much to add to find the missing number:<\/p>\n\n\n

The missing number is 12.<\/p>\n<\/div><\/div>\n\n\n\n
