1. First way to solve it:

Let x be the first of the three numbers.
Then the second and the third are (x+1) and (x+2), respectively.

Your equation is

x + (x+1) + (x+2) = 963.

3x + 3 = 963,

3x = 963 - 3 = 960,

x = = 320.

Thus the first number is 320, the second is 321, and the third is 322.

Please check yourself that the tree numbers satisfy the condition.

2. Second way to solve it:

Let x be the second number.
Then the first and the third numbers are (x-1) and (x+1), respectively.

And your equation is

(x-1) + x + (x+1) = 963,

3x = 963,

x = = 321,

and so on . . .

Good luck!
