At first glance, it seems almost too easy — a straightforward numerical sequence. But look a little closer, and you’ll realise it’s not as obvious as it first appears. What looks like a simple pattern may in fact be a cleverly disguised logic puzzle, one that demands you think outside the box.

“IQ Test: 11 = 8, 22 = 64, 33 = 216, 44 = ?”
