Things are not always as perfect as they seem…So says this number puzzle. Initially appearing as a simple count-up sequence, it actually has two missing numbers. The human brain, adept at adapting to common sights and thoughts, often overlooks details in familiar images.

The brain’s tendency to perceive patterns quickly leads to oversights, as seen in the seemingly complete number sequence above. It may take multiple tries to identify the missing numbers, revealing the brain’s complex problem-solving abilities.
I’m sure you’ve noticed there’s no 11 by now
This brain teaser challenges assumptions by hiding numbers within a seemingly straightforward sequence. The unexpectedly missing 11 may elicit surprise upon discovery, highlighting the brain’s capacity for rapid pattern recognition.
The structure of the sequence, with closely clustered numbers in horizontal groups, adds to the challenge of spotting the missing numbers. Despite this, attentive scrutiny reveals the absence of 11 and subsequently 32 within the sequence.
