Video Summary

A computer writes the numbers 1 through 7,000 consecutively with no separators, and the question asks how many times the digit sequence <strong>2026</strong> appears. The reasoning checks all possible ways the four digits could appear: entirely within one number, or split across adjacent numbers. It rules out cases that would require a leading zero, then identifies valid boundary crossings such as between 2620 and 2621, and between 6202 and 6203. It also includes the standalone number 2026. Altogether, the sequence <strong>2026</strong> appears <strong>three times</strong>.
