Step-by-step explanation:
this is clearly not a linear sequence (the terms don't have the same difference).
so, it has to be a geometric sequence.
the common ratio is r.
s2 = s1 × r
16 = 64 × r
r = 16/64 = 1/4
control :
s3 = s2×r
4 = 16 × 1/4 = 4
correct.
Answer by JKismyhusbandbae: expression 2 and expression 1
Look at the four expressions. Simplify any expressions that can be simplified to see which two are equivalent.
8v × 30v = ( 8 × 30) × ( v × v) = 
Since expression 2 can be simplified to expression 1, they are equivalent.
Answer:
As per the statement: the value of the expression 7 x n/4 greater than 7.
To describe the relationship between n and 4.
"greater than" symbol is represented by '>'
The value of expression
grater than 7 is;

Divide by 7 both sides we get;

Multiply both sides of an equation by 4 we get;

Therefore, the relationship between n and 4 is,
