Please help me it’s due tomorrow and I really need help
Anna35 [415]

Answer:

5 \frac{1}{3}, 10 \frac{2}{3}

Step-by-step explanation:

There is a common ratio r between consecutive terms, that is

\frac{2}{3} ÷ \frac{1}{3} = 1 \frac{1}{3} ÷ \frac{2}{3} = 2 \frac{2}{3} ÷ 1 \frac{1}{3} = 2

Thus to obtain a term in the sequence multiply the previous term by 2, thus

a₅ = \frac{8}{3} × 2 = \frac{16}{3} = 5 \frac{1}{3}

a₆ = \frac{16}{3} × 2 = \frac{32}{3} = 10 \frac{2}{3}

The product of two consecutive positive odd numbers is 195.By constructing a quadratic equation and solving it, find the two num
Tomtit [17]

Step-by-step explanation:

x = one odd number

the second odd number is (x+2), as both are consecutive.

so,

x × (x + 2) = 195

x² + 2x = 195

x² + 2x - 195 = 0

the formula to solve this is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = 2

c = -195

x = (-2 ± sqrt(4 - 4×1×-195))/(2×1) =

= (-2 ± sqrt(4 + 4×195))/2 = (-2 ± sqrt(784))/2 =

= (-2 ± 28)/2 = -1 ± 14

x1 = -1 + 14 = 13

x2 = -1 - 14 = -15 which is invalid as the numbers are positive.

so, the two numbers are 13 and 15.
