Step-by-step explanation:
Let us assume the four numbers as a, b , c , d.
given that ,
( a + b + c + d ) / 4 = 71.5
( 58 + 76 + 88 + d ) / 4 = 71.5
( 222 + d ) = 71.5 x 4
222 + d = 286
d = 286 - 222
d = 64
that means the fourth number is 64
I hope this may be helpful to you clearly
Thank you ☺️

Answer:
Let the fourth number be x.
(58+76+88+x)/4 =71.5
58+76+88+x =71.5×4
222+x =286
x =286-222
= 64
The fourth number is 64
