Answer:
Option 1 is a geometric sequence.
I 1/4, 1/4, 1/4, 1/4
II 1/4, 1/5, 1/6
III 1/4, 1, -4, 1/6
IV 1/4, -4, 1/4, -4
For any geometric sequence there should be a common ratio
To find common ratio we divide consecutive terms
lets check option I
I 1/4, 1/4, 1/4, 1/4
When we divide 1/4 by 1/4 we will get 1
Same 1 for other two terms, so common ratio is 1
Hence the first option is a geometric sequence

Answer:
A pentagon.
Step-by-step explanation:
A pentagon is a 5-sided polygon. Its interior angles each are equivalent to 108°.
108° ≥ 90°, so the angles are obtuse.
Therefore, a 2-D shape with 5 obtuse angles is a <u>pentagon</u>.
The book is 540 pgs.....she has read 405....that leaves (540 - 405) = 135 pgs left to read.
135 / 540 = 0.25 = 25% <== what she has left to read
Answer:


Step-by-step explanation:
Given
Let
f = Father's age
s = Son's age
We'll solve this question, while reading through the instructions
From the first statement;
f is 2 less than 7 times s.
This means

In two years time, the father will be f +2 and the son will be s + 2
So, their sum is:


Collect like terns


So, the equations are:
