It's important to keep your mind active, and engaging in stimulating activities throughout the day can encourage this. To help out, Wizeprep has taken to social media to challenge you to a brainteaser designed to determine whether you have a high IQ.

The task is simple: distribute the numbers one to nine across nine circles that surround a triangle so that every side equals 17. No number can repeat itself – it's a test of numerical mastery!

A video introducing the challenge says: "If you can solve this brainteaser, you are a math wizard. The rules are simple, place the numbers one to nine in the circles below so that every side adds up to 17. Every number must be used – so no repeating numbers."

Are you ready to take on the challenge? Pause for a moment and attempt to crack the code before peeking at the solution below. According to Mindvalley, "lateral thinking is a form of problem-solving that utilizes a more creative, less direct approach to the problem."

A statement reads: "The brain is neuroplastic, meaning it has the ability to shift and change over time.

"Many people believe our brains age as we do, growing less powerful, less capable, and less competent over time. What most don’t realise, however, is that you have the ability to manipulate your brain the way a sculptor moulds clay.

"The brain is susceptible to all we expose it to—people, music, work—even the physical environments we traverse on a day-to-day basis. Everything we partake in has the potential to subtly shift the wiring of our brain."

One user triumphantly revealed the solution, stating: "Right side top down 1, 9, 5, 2 = 17 Left side top down 1, 6, 7, 3 = 17 Bottom left to right 3, 4, 8, 2 = 17."

Another participant boasted about their quick solving skills: "Took me five minutes. I feel nice."

A third chimed in with a strategic hint: "To solve it, the key is that 1 to 9 sum 45 and 3x17 is 51, so numbers in the corners must sum 6= 1+2+3. Finding the rest is straightforward..." Meanwhile, another solver expressed their enjoyment: "This was great. Thank you! ! I got it within three minutes."

Lastly, a helpful tip from another user pointed out: "Clue: 1 to 9 sum to 45. the three sets of 4 numbers add to 51 (3*17) therefore numbers totalling 6 are counted twice. those go in corners."
