Step-by-step explanation:
let the four integers be a, b, c, d
average of first two
a + b /2 = 102
a + b = 204 equ (1)
average of first three
a + b + c / 3 = 103
a + b + c = 309 equ (2)
average of all four
a + b + c + d / 4 = 104
a + b + c + d = 416 equ (3)
substitute equ (1) in equ (3)
309 + d = 416
d = 416 - 309
d = 107
substitute equ (1) in equ (2)
204 + c = 309
c = 309 - 204
c = 105
greatest of all the four is d = 107
hope you get your answer
