A student writes seven consecutive natural numbers and the sum of the smallest three number is 33, which of the following is the sum of the largest numbers?
Answer:
if the numbers are "a-1", "a", "a + 1". Then a = 33/3 = 11
so, the numbers are 10, 11, 12.
so the last three numbers are 14, 15, 16
sum of 14, 15, 16 = 45
Answer:
if the numbers are "a-1", "a", "a + 1". Then a = 33/3 = 11
so, the numbers are 10, 11, 12.
so the last three numbers are 14, 15, 16
sum of 14, 15, 16 = 45
