Answer:
The 8th term in the sequence is -128
Step-by-step explanation:
The given series is a geometric progression (G.P) with the starting term as -1.
Let the starting term be a and the common ratio be r.
a = -1
r = 2
The formula for the nth term of a geometric progression (G.P) :
n = 8
Therefore, the 8th term in the sequence is -128
Answer:
No, because 5 + 4 isn't greater than 10.
Step-by-step explanation:
Given

Do they form a triangle
To check if they form a triangle or not, we make use of trinagle inequality theorem which states that; for sides a, b and c
So for sides 4, 5 and 10, we have:
--- False
<em>Since the one of the inequalities is false, then the sides do not form a triangle.</em>
