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?1). 332). 313). 354). 29

Answer»

Let 7 odd CONSECUTIVE numbers are (n - 6), (n - 4), (n - 2), n, (n + 1), (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
