In mathematics, the look-and-say sequence is the sequence of integers beginning as follows: 1, 11, 21, 1211, 111221, 312211, 13112221, 1113213211, ... (sequence A005150 in the OEIS). To generate a member of the sequence from the previous member, read off the digits of the previous member...
The Look and say sequence is a recursively defined sequence of numbers studied most notably by John Conway. Sequence Definition. Take a decimal number. Look at the number, visually grouping consecutive runs of the same digit.
The look and say teaching method, also known as the whole word method, was invented in the 1830s and soon became a popular method for teaching reading.

look and say noun (education). A method of teaching reading, whereby the pupil is trained to recognize words at a glance, and say them, rather than articulate the letters of the word one by one.
Look and say sequence is the sequence of numbers generated from the previous number by reading off the digits of which the number consists.
