21, 22, 23, 24

consecutive integers

let say its x, x+1, x+2, x+3

(because its consecutive)

it says the sum of the 2nd and 3rd is 24 more than a half of the smallest which is the first one or

it means:

(x+1) + (x+2) = x + 24

2x + 3 = x + 24 (simplify by its terms)

2x -x = 24 -3 (combine like terms)

x = 21 (simplify)

if x is 21

substitute x with 21

1st# or X = 21

2nd# or X+1 = 22

3rd# or X+2= 23

4th# or X+3 = 24

checking:

2nd + 3rd = 1st +24

22 + 23 = 21 + 24

45 = 45

hope this solve the problem
