Please help me with the question below

If the numbers are consecutive multiples of 6, and you want to call the smallest one ' n ', then the next one is (n+6) and the biggest one is (n+12).

Their sum is (3n + 18).  That's choice-C .

If you run into the same problem again, you might like to call the middle number ' n '.  Then the smallest one is (n-6) and the biggest one is (n+6),

and their sum is just 3n !  This is a lot easier to do in your head.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
