a. the missing number is 47 to find it you have to x 2 to it to get the next number

B.the m issing number is 26 to find these you have to add 2 the number that you just added to the number ex. 1 +2 = 3+2=5 and so on

a:47 and the pattern is doubling the # before that!

b:26 the pattern is that they r just counting by the odd #'s

Anonymous said...

A= 47 because if you add up it has to equal a number the previos numbers can go into.

B= 26 because you have to add the next odd number to the previos number.

A=You add the number to equal the answer and double the number to get the other answer.it Equals 47.


B=You add the odd numbers and the number would be 26.

A. 47
pattern: +3+6+12+24etc. {just keep doubleing}

B. 25
pattern:+1+3+5+7+9 {skip a number each time}

Anonymous said...

47 cuz it is timesing by 3
26 it timesing by odd numbers

Anonymous said...

47 and 26 because you keep doubling and that is how you get the answer

Anonymous said...

In A. the rule is x 2 plus one so the next number would be 47, because 23x2= 46 + 1 =47

In B. the rule is you keep adding the next odd number to the previous number so the next one would be 26 because 17+9 =26 :)

33 because i just guessed because i couldnt figure it out

Anonymous said...

the first one is 47 because you double the number then add 1

the rule for A is multipe by 2 and add 1 giving you 47

the rule for B is add the odd number giving you 26

Austen Iverson-South Dakota said...

The First one is 47 because its times 2 plus 1

The second one is 26 becuase its odd numbers like add 3, then, 5,7,9 and so on

Anonymous said...

A: is you time it by two and then add one so the answer should be 47


B:you double it then you double it and add one so 35
