Math patterns example 1 | Applying mathematical reasoning | Pre-Algebra | Khan Academy

Part of our exploration of math is learning to identify patterns among numbers. Can you see the pattern in this example?

Missed the previous lesson?

Pre-Algebra on Khan Academy: No way, this isn't your run of the mill arithmetic. This is Pre-algebra. You're about to play with the professionals. Think of pre-algebra as a runway. You're the airplane and algebra is your sunny vacation destination. Without the runway you're not going anywhere. Seriously, the foundation for all higher mathematics is laid with many of the concepts that we will introduce to you here: negative numbers, absolute value, factors, multiples, decimals, and fractions to name a few. So buckle up and move your seat into the upright position. We're about to take off!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

Khan, years ago you taught me remedial algebra, then algebra, and I moved to to complete calculus, with an A. I went from to community College, to University of Oregon, and am now a biologist tagging sea turtles for NOAA, sending this message of gratitude from the middle the ocean on a fishing vessel about a thousand miles north of Oahu. Cheers, Khan.

f(n) = 4n + 2. The +2 represents 2 sides. 4n represents the max per table.

Thank you khan academy this video helps me a lot about patterns in math subject!

[alexanderrana]

this video deserves more likes


cause it' so interesting

[jonathan]

Bro this man is about to save my grades

Having mathematical errors in math lessons isn't cool, its confusing already confused learners lol

So we have y=4x+2..y is the number of people and x number of table

[leenamahase]

thanks for posting maths so I can understand

[matthew]

um....you added 5 not 4 +5 = 23 not 22 but good point i like it

[zakkiuk]

did anyone else notice how at da end he wrote 18+5 instead of +4

[rumanafariha]

In the last term you added 5. (+5) ??!!

[sunnyhe]

what software thing is he using to draw/show all of this?
