Question
If the average of 7 back-to-back numbers is 65, find the
sum of the first and last numbers.Solution
ATQ,
Assume the numbers are: (a - 3), (a - 2), (a - 1), a, (a + 1), (a + 2), (a + 3)
Then, (a - 3 + a - 2 + a - 1 + a + a + 1 + a + 2 + a + 3) ÷ 7 = 65
⇒ (7a / 7) = 65
⇒ a = 65
Sum of smallest and largest = (a - 3) + (a + 3) = 2a = 2 × 65 = 130
