Answer 2

4-0 = 80

Step-by-step explanation:

If  1 - 0 = 10                 2-0=40 then

    3-0 = 30     and        then 4 - 0 = ?

for odd Numbers like 1, 3 and 5...

It was first  multiplied by 10.

1 →  10  3 → 30  5  → 50

For even Members like 2, 4,6 ben It was just doubled and multiped  by 10

10. (i.e.) 2 - 4 × 10 → 40

    then for 4 → 8 × 10 → 80.

                      ↓

       therefore 4-0 = 80
