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
