The next number in the pattern is 48. This pattern adds multiples of three to the existing number.

3 + (3 x 0) = 3

3 + (3 x 1) = 6

6 + (3 x 2) = 12

12 + (3 x 3) = 21

21 + (3 x 4) = 33

33 + (3 x 5) = 48

etc.

What is the next number 3-6-12-21?

The pattern in the sequence 3, 6, 12, 21 can be identified by examining the differences between consecutive terms: 6-3=3, 12-6=6, and 21-12=9. The differences (3, 6, 9) are increasing by 3 each time. Continuing this pattern, the next difference would be 12 (9 + 3). Therefore, the next number in the sequence is 21 + 12, which equals 33.

What is x for -4x plus 3(x-7)-12?

To solve for ( x ) in the equation (-4x + 3(x - 7) - 12 = 0), first distribute the 3: (-4x + 3x - 21 - 12 = 0). Combine like terms: (-4x + 3x - 21 - 12 = -x - 33 = 0). Solving for ( x ), we get ( -x = 33), thus ( x = -33 ).
