Answer:
The formula means; a of the next arithmetic n equals to 5 multiplied by a of the preceding n knowing that a of when n=1 is 2 and n must be 1 or greater than 1.
Step-by-step explanation:
a(n + 1) = 5* a(n) for n≥1
given that
a(1) = 2
therefore:
when n = 1, a(2) = 5* a(1) = 5 * 2 = 10
when n = 2, a(3) = 5*a(2) = 5 * 10 = 50

Answer:
x= -1/9
Step-by-step explanation:
6+2x=5-7x
-2x. -2x
6=5-9x
-5. -5
1=-9x/-9
-1/9=x
Step-by-step explanation:
In the following triangle, a= ? , b= 2cm.
m<B= 105° , m<C = 15° ,m< A =?
Now, we know that sum of the interior angles of the triangle = 180°
m<B+m<C +m< A =180°
105°+15°+m< A=180°
m< A= 180- 120° = 60°
Answer:
3x ＞ 37
