A.
Eqn 1 - Eqn 2:
x + 3y - (x + 2y) = 18 - 14
x + 3y - x - 2y = 4
y = 4

Substitute y = 4 into Eqn 1 (You can also do this with Eqn 2 instead)
x + 3(4) = 18
x = 6

Thus, (6,4)

A geometric sequence has u4= -70 and u7=8.75<br> Find the second term of the sequence.
Kobotan [32]

Answer:

-122.5

Step-by-step explanation:

Difference = 7 - 4 = 3 terms; 8.75 - (-70) = 78.75

1 term → 78.75/3 = 26.25

therefore, u2 = - 70 - 2(26.25) = -122.5
