7X=28
X=28/7
X=4

What is the 18th term of the arithmetic

Irina18 [472]

Answer:

J

-66

Step-by-step explanation:

a1 = 2

n = 18

d = - 4

a18 = a1 + (n - 1) * d

a18 = 2 + (18 - 1)*(-4)

a18 = 2 + 17*-4

a18 = 2 - 68

a18 = -66

M is the MIDPOINT OF FG. FG = 26 AND GM = (3X - 2)

vova2212 [387]

It is given in the question that

M is the MIDPOINT OF FG.

$FG = 26 \ AND \ GM = (3X - 2)$

Since M is the midpoint of FG, therefore GM is half of FG. That is

$3X-2 = \frac{1}{2} (26)$

$3X-2 =13
\\
3X = 15
\\
X =5$

Therefore

$GM = 3(5) -2 = 13$

And FM is 13 too .
