1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 = 66
So if 66 terms come before the first "12", the first "12" will be the 67th term.

i don't understand i thought that every number is being repeated by it's no. like for an example 1 is written 1 time 2 is written two times then 12 should be written 12 times that's what i understood from the question and obviously what i've got from the question is incorrect so please can you help me more with understanding it with a different method than that one thanks a lot i would really appreciate it if you would answer my SAT is tomorrow and I'm already panicking
ReplyDeleteNo, you understand it right. When does the first 12 come? It comes after 1 1, 2 2s, 3 3s, 4 4s, 5 5s, etc. The first 12 will be after 1 + 2 + 3 + ... + 11 terms.
