math sequence ?

Question

1, 2, 4, X, X, X, 22

What are the x's. I couldn't figure this out to help my daughter (5th grade) with her homework and it's bugging me! Also, what is the rule for this. Thanks!

Thanks guys!!! I didn't think it would be too hard to figure out, but I'm HORRIBLE at these things!

Answer 1

I will answer your question, (but be warned, you may feel really silly).

1,2,4,7,11,16,22
The "rule" look for the pattern. This particular one incrementing
by one at each step 1,2 (3) 4 (5,6) 7, (8,9,10) 11, (12,13,14,15) 16, (17,18,19,20,21) 22

Answer 2

1, 2, 4, 7, 11, 16, 22

+1/ +2/ +3/ +4/ +5/ +6

Answer 3

the seq. is 1,2,4,7,11,16,22

1
1 + 1 =2
2 + 2 =4
4 + 3 =7
7 + 4 =11
11+5 =16
16+6 =22

Answer 4

Waldo maths isn't a foul information superhighway website. You do sequences in 365 days 11 yet i'm undecided that series is on the curriculum. i imagine of the major ingredient you want is calling the nth time period of a series & that's on Waldo maths. sturdy fulfillment!

Answer 6

First of All, if there only 3 blanks between the numbers???
Try this then: (This is a T-chart)

---Term------1----Number------
-----1---------1-------1--------------
-----2---------1-------2-------------
-----3---------1-------4-----------------
-----4---------1----------------------
-----5---------1-----------------------
-----6---------1-----------------------
-----7---------1-------22--------

See if you can see any patterns there!
That's what my math teacher taught me!
Good Luck!
Ok I think this is way too complicated!
+1/+2/+3/+4/+5/...............
