Answer» For given dsts 6, 7, x-2, x, 17, 20 mean is average of(6/2)th and [(6/2) + 1]th term Thus, mean = (x - 2 + x)/216 = (2x - 2)/22x = 32 + 2x = 34/2 = 17 Value of x is 17

Answer»

For given dsts 6, 7, x-2, x, 17, 20 mean is average of(6/2)th and [(6/2) + 1]th term

Thus, mean = (x - 2 + x)/216 = (2x - 2)/22x = 32 + 2x = 34/2 = 17

Value of x is 17
