Step by Step Written Solution
In this problem, we are asked to find the next number in the sequence. Let's look at the pattern carefully.
Number Sequence Problem
The sequence starts with the number four. In the next step, a five is added to the front to make fifty four.
In the third step, the number six is added to the front, giving us six hundred and fifty four. Notice that we are adding consecutive numbers in decreasing order to the left of the existing digits.
Pattern: Add the next higher digit to the left.
The sequence follows this rule: first we have four, then we add five to get fifty four, then we add six to get six hundred and fifty four.
