Find the missing number
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 77
In each figure the centre number is made from the four outer numbers by one rule: left \(\times\) right \(+\) top \(+\) bottom. The rule is found on the first figure and confirmed on the second.
First figure: \(5\times8+9+3=40+12=52\)
Second figure: \(9\times3+11+8=27+19=46\)
Third figure: \(9\times6+15+8=54+23=77\)
