You need to find a way to add two numbers which make the number in the units column. And the tens as well.

answers You need to find the pattern
1.a Between 700 and 800
363 726,707,766,787,800,747,727,726,746,786
462 Between 300 and 400
561 363,383,323,343,303,322,302,342,362,382
1.b Between 800 and 900
403 808,828,848,868,888,807,827,847,867,887
502
