Pattern ka rule dhoondo
3, 7, 11, 15 ... agla number kaunsa hoga, aur bina ginti kiye kaise bata sakte ho?
Socho pehle… phir dekho jawab
19! Kyunki rule hai 'har baar 4 jodo'. Rule pakad lo toh kitna bhi aage ka number bata sakte ho.
Pattern ek aisi line hai jisme har number kisi rule se aata hai. 3, 7, 11, 15 mein har baar 4 jodte hain. Rule dhoondne ke liye do paas-paas ke numbers ka antar dekho: 7 - 3 = 4, 11 - 7 = 4.
Pattern ghat bhi sakte hain: 20, 17, 14, 11 mein har baar 3 ghatate hain.
Cause-effect: 5 ke table 5, 10, 15, 20, 25 mein har baar 5 jodte hain, isliye ant mein ek baar 5 aur ek baar 0 aata hai. Rule samajh lo, toh pattern ki bhavishyavani sahi hoti hai.
Ghar pe try karo
Kaagaz par bindiyon ki lines banao: pehli line mein 1, doosri mein 3, teesri mein 5. Chauthi line mein kitni bindi aayengi? Rule likho.
Wow!
Rule pata ho toh 100wan number bhi bina saare number likhe pata chal jaata hai!
Mummy-Papa ke liye
Aaj bachche se bindiyon ka pattern banwaiye aur poochiye: 'Rule kya hai? Agli line mein kitni bindi?'
