which 4?

Now am also thinking one more thing which shows it can be 6 too. See how:

In the last row, descending series of 8 to 3 had skipped the next digit after 5 (i.e. 4) as you can see its 3 after 5 in green, so we should do the same in solution and while multiplying (see the numbers in blue) in descending order to get the products, we should skip 3 there in the last row and instead multiply it with next digit after 3 i.e. 2

[COLOR="SeaGreen"]8[/COLOR]*[COLOR="Blue"]7[/COLOR]=56
[COLOR="seagreen"]7[/COLOR]*[COLOR="blue"]6[/COLOR]=42
[COLOR="seagreen"]6[/COLOR]*[COLOR="blue"]5[/COLOR]=30
[COLOR="seagreen"]5[/COLOR]*[COLOR="blue"]4[/COLOR]=20
[COLOR="seagreen"]3[/COLOR]*[COLOR="blue"]2[/COLOR]=6

Simplifying more, we can get the answer by following the pattern of multiplying each number with the number lower to it.
Correct me if I am wrong

8*7=56
7*6=42
6*5=30
5*4=20
4*3=12
3*2=6
2*1=2
