Arithmatic mean = sum/members 

=> (1x1 + 2x2 + 3x3 + 4x4 + 5x5 + 6x6 + 7x7) / (1 + 2 + 3 + 4 + 5 + 6 + 7)

=> 140/28 = 5

Step II     : 43   31   03   22   11   09
Step III   : 43   31   22   03   11   09
Step IV   : 43   31   22   11   03   09
Step V    : 43   31   22   11   09   03

From (i) and (ii),   a leap  =>  ki mo       --------(iv)

From (i) and (iii),  frog's   =>   ja           ---------(v)

From (i), (iv) and (v),  'at' => pe

Given word : CONTEXTUAL

After making changes as per given in the question , the above word becomes as follows:
