yes sir... can u pls im thanking u in advance

anonymous · Answer

first digit is 12 
last digit divisible by 6 within 195 is 192
so the difference is 6
using formula find out
the no. of digit$$n= \frac{ l-a }{ d} +1=\frac{ 192-12 }{ 6 } +1 =31$$

anonymous · Answer

then using the summation formula 
sum$$=\frac{ n }{ 2 }\left( 2a+\left( n-1 \right) d\right)$$


$$\frac{ 31}{ 2 }(24+(14)6) =3348$$
