Step-by-step explanation:
1
(x + 5)² = 4 ( take the square root of both sides )
x + 5 = ± = ± 2 ( subtract 5 from both sides )
x = - 5 ± 2, thus
x = - 5 - 2 = - 7
x = - 5 + 2 = - 3
--------------------------------------------
2
(x + 6)² = 7 ( take the square root of both sides )
x + 6 = ± ( subtract 6 from both sides )
x = - 6 ± , thus
x = - 6 -
x = - 6 +
------------------------------------------------
3
(x - 2)² = 18 ( take the square root of both sides )
x - 2 = ± = ± = ± 3 ( add 2 to both sides )
x = 2 ± 3, thus
x = 2 - 3
x = 2 + 3

Answer:
Step-by-step explanation:
The common difference is 7
Since the common difference is 7
a_n = 12+(n-1)7
a_n = 12+7n -7
a_n = 5+7n
