Answer 1

see this puzzle follows a certain pattern i.e ,

add all numbers around the circle amd square the result the result is equal to the middle number of the circle .let's check,

1st circle :

sum of all numbers present around it = 7+3+2+1 = 13 . squaring the result = 13×13 = 169 = middle number of first circle

2nd circle :

sum of all numbers present around the circle = 5+3+2+1 = 11 . squaring the result which is equal to 11×11 = 121 = middle number

now,

middle number in third circle = 6+5+4+1 = 16 squaring the result 16×16 = 256

∴ Answer is 256
