Answer:
a. The common ratio is 0.5
b) The value of the first term is 29
c) The sum of the first 5 terms is 56.1875
Step-by-step explanation:
The nth term of the geometric sequence is a = a, where
The sum of the nth term is S =
∵ The second term of a geometric sequence is 14.5
∴ n = 2
∴ a = 14.5
∵ a = ar
→ Equate the right sides of a by 14.5
∵ ar = 14.5 ⇒ (1)
∵ The fifth term is 1.8125
∴ n = 5
∴ a = 1.8125
∵ a = a
→ Equate the right sides of a by 14.5
∵ a = 1.8125 ⇒ (2)
→ Divide equation (2) by equation (1)
∵ =
∴ r³ = 0.125
→ Take ∛ for both sides
∴ r = 0.5
a. The common ratio is 0.5
→ Substitute the value of r in equation (1) to find a
∵ a(0.5) = 14.5
∴ 0.5a = 14.5
→ Divide both sides by 0.5
∴ a = 29
b) The value of the first term is 29
∵ n = 5
∴ S =
∴ S = 56.1875
c) The sum of the first 5 terms is 56.1875
Answer:
3.86
Step-by-step explanation:
7 times a number is 27...
We can find that number by dividing 27 by 7
27 / 7 = 3.86
