Answer 2

Step-by-step explanation:

let x be the sum of 3 consecutive numbers so

number are,

x, x+1, x + 2

so,

→ x + x + 1 + x + 2 /3 = 52

→ 3x + 3 /3 = 52

→ 3x + 3 = 52 × 3 = 156

→ 3x = 156 - 3

→ 3x = 153

→ x = 153/3 = 51

→ x = 51

therefore,

first consecutive number = 51

2nd consecutive number = x + 1 = 51 + 1 = 52

3rd consecutive number = x + 2 = 51 + 2 = 53

now sum of all the three consecutive numbers are,

51 + 52 + 53 = 156.

hence option b is correct.

hope this answer helps you dear!
