ANSWER
No, because there is no common ratio
EXPLANATION
The given sequence is
-1, 1, 4, 8
If this sequence is geometric, then there should be a common ratio among the consecutive terms.

Hence the sequence
-1, 1, 4, 8
is not a geometric sequence.

Answer:
Volume of emerald = 137.04cm³
Step-by-step explanation:
Given that:
Mass of emerald = 378.24grams
Density of emerald = 2.76grams/cm³
Volume = ?
The equation for this relationship is ρ = m / V in which ρ is density, m is mass (kg or g) and V is volume (cm³ or m³) making the density unit kg/m³ or g/cm³.
Therefore
Density = mass/volume
Volume = Mass/density
i.e
Volume of emerald = Mass of emerald / Density of emerald
Volume of emerald = 378.24grams / 2.76grams/cm³
Volume of emerald = 137.043cm³ ~137.04cm³
Volume of emerald =137.04cm³
