if you add the digits in a 3s count-by, the total will be 3,6 or 9? True or False

OpenStudy (anonymous):

What's a count-by?

OpenStudy (anonymous):

I am guessing 3, 6, 9 and so on

OpenStudy (anonymous):

for my second grade son.

OpenStudy (anonymous):

he has to determine if it is true or false. If true show 3 examples if false show one

OpenStudy (anonymous):

Haha. It's kind of comical that I can answer calculus problems but not this one. If the sequence is 3,6,9,etc... the sum will definitely exceed 3, 6, or 9. So the answer is false. Somehow I don't think the question is asking this.

I feel the same as his 45 yr old dad. Can I get adifferent problem to help him with. Lol

OpenStudy (anonymous):

figured it out. The next number in the series is 12 add those digits of 1+2 and you get 3, 15 add them you get 6 and so on

OpenStudy (anonymous):

Ohhhhhhh.

OpenStudy (anonymous):

I was way over thinking this one. lol

OpenStudy (anonymous):

thanks

OpenStudy (anonymous):

Haha no problem.
