Answer 2

@RadEn Can you please help me?

Answer 3

connections?

Answer 4

Is the answer 752? That is what I got when I solved it.

Answer 5

well, this like we want get the sum of :

for n = 1 then 6(1) - 4 = 2
for n = 2 then 6(2) - 4 = 8
for n = 3 then 6(3) - 4 = 14
.....
.....
so on till
for n = 16 then 6(16) - 4 = 92

add them, it like
2+8+14+20+...+92 = ... ?

Answer 6

What you showed is what I did! Thanks!

Answer 7

yes, by using Gauss methode, it can be
(92+2) * 8 = 752

you are right!
