What is the first four terms in the multiplication or ,geometric , pattern in which the first term is 2 and then each term is mu

sesenic [268]

Answer:

the sequence is 2, 14, 98, 686.

Step-by-step explanation:

As we know in any geometric sequence the terms are denoted by

$T_{n}=a(r)^{n-1}$

We have to find the first four terms of geometric sequence which has first term a = 2 and common ratio of the terms r = 7

number of terms = 4

The sequence from the formula will be

$2, 2.7, 2.(7)^{2},2.(7)^{3}$

or the sequence is 2, 14, 98, 686.

A pair of equations is shown below.

Zolol [24]

I'll solve it by substitution instead of graphing.

x + y = 2
y = (1/2)x + 5

Substitute equation 2 into equation 1.

x + (1/2)x + 5= 2

(3/2)x + 5 = 2

(3/2)x + 5 - 5 = 2 - 5

(3/2)x = -3

(2/3) * (3/2)x = -3 * (2/3)

x = -2

x + y = 2
-2 + y = 2
y - 2 = 2
y - 2 + 2 = 2 + 2
y = 4

x = -2
y = 4

(-2,4)

Your answer is B) (-2,4).
