the sum of the first ten terms of an arithmetical progression is 255 find the sum of the next twenty terms of the progression given that the sum of the first twenty terms of the progression is 1020​

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
