MEAN OF X = 16      MEAN OF Y = 6.57

Step-by-step explanation:

ARITHEMETIC MEAN = Arithemetic mean of numbers is defined as the ratio of the sum of all the numbers to to the total numbers.

It is abreviated as AM.

For a set of numbers, AM = \frac{n1+n2+n3+n4+n5..........}{N}

Where N is the total numbers in the set.

X 10,12,14,16,18,20,22        N = 7

  AM = \frac{10+12+14+16+18+20+22}{7}

AM = 16

Alternatively for X  as all the numbers are evenly distributed hence the mean will be the central number of the set . this is only applicable for evenly distributed numbers.

Y 4,5,8,16,7,4,2           N = 7

 AM = \frac{4+5+8+16+7+4+2}{7}

 AM = 6.57
