Evaluate [4.8]. (remember the brackets represent the greatest integer function.) write your answer as a single number. evaluate [-2.7]. (remember the brackets represent the greatest integer function.) write your answer as a single number.

Greatest integer function returns the largest integer values less than or equal to that number

for example : [7.7] = 7

[2.6] = 2

[-6.3] = -7

We round the number to the nearest whole number less than the given number

Evaluate [4.8]

 [4.8] = 4 , nearest whole number less than 4.8 is 4

Evaluate [-2.7]

[-2.7] = -3, nearest whole number less than -2.7 is -3

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
