Answer:
decreasing, non-increasing
Step-by-step explanation:
The sequence is ...
1, 1/2, 1/3, 1/4, ...
Each term is smaller than the one before it, so the sequence is decreasing (also, non-increasing).
conditions : x≠0 and x≠-a and b≠1
1/(x+a) = b/x ⇌ 1×x = b(x+a) ⇌ x = bx + ba ⇌ (1-b)x = ab ⇌ x = ab/(1-b)
[3*(2+4)] -4
Parenthesis first:
[3 * 6] -4
Brackets next:
18 - 4
Now subtract:
18-4 = 14
The answer is C. 14
