Question

Find the three conescutive whole number shoes sum is more than 45 but
Less than 54

Answer 1

n + (n+1) +(n+2) = lets say, 45

3n + 3= 45

n = 42/3 = 14

if 3 n + 3 = 54

n = 17.

hence the limits for n are 14 <n<17

thus three consecutive numbers can be (15 16 17) or (16 17 18)

clear?

hope so☺️
