The “look and say sequence” is defined by reading off the previous number, counting the digits in a consecutive group – then using that number as the next term. For example, this is the look and say sequence beginning with 1:
- 1 is read as “one 1”, or 11, so the next term is 11
- 11 is read as “two 1s”, or 21, so the next term is 21
- 21 is read as “one 2, then one 1”, or 1211, so the next term is 1211
Find the 8th term (including the first, 1-digit term) of the look and say sequence beginning with 3.
