Answer 2

Answer:

b) 36

Step-by-step explanation:

let the first observation be X

then second one =X+4

third one =X+4+4=X+8

fourth one =X+8+4=X+12

fifth one =X+12+4=X+16

as per the problem ,

(X+X+4+X+8+X+12+X+16)÷5=28

(5x+40)÷5=28

5x+40=28*5

5x+40=140

5x=140-40

5x=100

X=100/5

X=20

therefore the observations are 20,24,28,32,36.

the largest observation =36.

therefore the answer is 36.
