AlladinOne [14]3 years ago
6 0

Step-by-step explanation:

multiply ,1 st x 2 and 2nd x 3

so,

10 X2 + 6y2 = 136

12 X2 - 6y2 = - 48

________________

22 X 2 = 8 8

X 2 = 88 / 22

X2 = 44

X= ± 2✓ 11

y 2= 96

y = ± 4✓ 6

The first terms of a geometric sequence are as follows.
Flauer [41]

The fourth and fifth term of this sequence is -30 and -10 respectively.

Data;

  • first term (a) = -810
  • common difference (r) = ?

<h3>Common Difference</h3>

The common difference in a geometric progression is the ratio between two successive terms.

Let's find the common difference in this sequence

r = \frac{-270}{-810} \\r = \frac{1}{3}

The nth term of a geometric sequence is given as

T_n = ar^n^-^1\\

The next two terms of this sequence will be 4th and 5th term.

The fourth term of this sequence is

T_4 = ar^4^-^1\\T_4 = -810 * (\frac{1}{3})^3\\ T_4 = -810 * \frac{1}{27}\\ T_4 = -30

The fifth term of this sequence is

T_5 = ar^5^-^1\\T_5 = -810 * (\frac{1}{3})^4\\T_5 = -810 * \frac{1}{81} \\T_5 = -10

The fourth and fifth term of this sequence is -30 and -10 respectively.
