To solve this, we can use a combinatorial approach. We want to form an 8-digit number using the digits 3 and 4, with exactly three consecutive 3's. Let's break it down:
Position the block of three consecutive 3's:
The block "333" can start at positions 1 through 6 in the 8-digit number. This gives us 6 possible positions for the block.
