Find the first term and common ratio for the geometric sequence a2 =2.5,a4=62.5

fenix001 [56]

Answer:

a1 = 0.5; common ratio = 5

Step-by-step explanation:

Let the common ratio = r

a2 = 2.5

a3 = 2.5r

a4 = 2.5r * r = 2.5r^2

We are told a4 = 62.5, so

2.5r^2 = 62.5

Divide both sides by 2.5

r^2 = 25

r = 5

a2 = a1 * r

a1 = a2/r = 2.5/5 = 0.5

Answer: a1 = 0.5; common ratio = 5

Hint: Find the value of x first, then subsitute the answer into 2x- 24.

Artemon [7]

Step-by-step explanation:

$\because \: \angle \: BCD = \angle \: BFG \\ (corresponding \: angles) \\ \therefore \: x + 26 \degree = 2x - 24\degree \\ \therefore \: x - 2x = - 26 \degree- 24\degree \\ \therefore \: - x = - 50\degree \\ \therefore \: x = 50\degree \\ \\ \therefore \: m \: \angle \: BFG = 2x - 24\degree \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times 50\degree - 24\degree \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:= 100\degree - 24\degree \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:= 76\degree \\ Hence, \\ \huge \red{ \boxed{ \: m \: \angle \: BFG =76\degree }}$
