Please in an arithmetic mean
a, A_1 , A_2 , A_3 , ... , A_n , b
where A_1 , A_2 , A_3 , ... , A_n are nth arithmetic mean
why is b = (n + 2)th term: like T_(n + 2)
Please
in solving the linear congruence
ax ≡ b (mod n) ⇒ n∣(ax − b) ⇒ ax −b = kn ⇔ ax −kn = b
⇒ solving the linear diophantine equation ax −kn = b
what are the general solution to the equation
ax−kn = b
