Step-by-step explanation:
\[d=a_{n}-a_{n-1}=4\]
a1=12
a7=a1+(7-1)d=12+6×4=12+24=36
The vertical lines are absolute values, the number in between them, if negative turns positive.
We have to solve x in terms of a, b and c:
a x - 3 b = c
a x - 3 b + 3 b = c + 3 b
a x = c + 3 b
x = ( c + 3 b ) : a
Answer:
4 ) ( c + 3 b ) / a
