# Finding patterns in numbers

This video discusses how to identify patterns in number sequences. By analyzing three different sequences, the speaker demonstrates that patterns can involve adding a certain amount to each number, or multiplying each number by a certain amount. It's important to ensure the pattern remains consistent throughout the sequence.

• In the 1st pattern isn't 67 + 21= 88 ?
Why is the next number 89 in the pattern?
• hi how are you doing?
• Can a pattern alternate? ie. Add three, then subtract five, then add three again, then subtract five, etc.
• Yes
for example -
1,2,5,6,9 (+1+3+1+3)
• How many patterns are in the world and not just numbers?
• thair are also patterns for shapes but i think u already now that

• I don't get it...can you help pls?
• So your pretty much just skip counting

• so ive seen alot of problem solving questions bring up patterns and try to predict the answer, but ive heard about some patterns that eventually fail, so is it actually reliable to look for patterns while solving some problems?
• whats next? 01110011 01110100 0110111 0111000
• this is binary numbers(number that, instead of having tens digit, hundreds digit etc. you have mutliple of 2s digits so 0 is 0, 1 is 1 but for 2 you consider no symbol for 2 so you now you have 0 ones and 1 two meaning 2 is 10 then adding another 1: 3 is 11, 4 is 100. it's basically you carry each time there's a two about to come instead of a ten)

it's an alternating pattern of adding 1 and 3 or in this case 1 and 11
