Answer 1

23+24+63+83+103+
123+143+163+183+203=1130

I hope ots correct

Answer 2

Step-by-step explanation:

so a=13

difference = d=23-13=10  

a+(n-1)*10= 13+10n-10=3+10n=2025

or 10n=2022

or n = 202.2

frm here u got n

now in the next series a=.11

difference =.11 ...try this method to get the solution. ..
