Finding Missing Numbers in Sequences

The video tutorial addresses a fill-in-the-blank problem involving a sequence of numbers. The teacher demonstrates how to identify the missing number by recognizing patterns in the hundreds place value. A number line is used as a visual aid to illustrate the increments of 100 between numbers. The missing number is determined to be 390, and the solution is verified by checking the pattern consistency. The tutorial emphasizes understanding place value and using visual tools to solve numerical problems.
