Hi Thokala, hope you're doing well. I’m Ian, and I’m happy to help you today.
You can do Offset to get the two above and two below cell values to get the average of it. Please sample code below. In this case we are look the Average of C7 based on the values of C5,C6, C8, C9 columns
=(SUM(OFFSET($C7, 1, 0, 2, 1)) +SUM(OFFSET($C7, -1, 0, -2, 1))) /4
You can also do a simple formula below. You sum the 5 columns and subtract the value of the column you want to average.
=(SUM($C5:$C9)-$C7)/4
