Average of 7 consecutive odd numbers is 31. If the previous and next odd number to these 7 odd numbers are also included, then what will be the new average?

Average of 7 consecutive odd numbers is 31. If the previous and next odd number to these 7 odd numbers are also included, then what will be the new average? Correct Answer 31

Let 7 odd consecutive numbers are (n - 6), (n - 4), (n - 2), n, (n + 2), (n + 4), (n + 6)

Given that, Average = 31

Average = middle term = n = 31

If we add previous and next odd number to these 7 odd numbers, again middle term will be

n = 31

∴ New average = 31
