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:
y = -4.3
Step-by-step explanation:
40 = -10(y + 0.3) <em>{Step 1: Use the distributive property to multiply -10 by y + 0.3}</em>
40 = -10y + -10(0.3)
40 = -10y - 3 <em>{Step 2: Add 3 to both sides.}</em>
40 + 3 = -10y
43 = -10y <em>{Step 3: Divide both sides by -10}</em>
43/-10 = y
-4.3 = y
y equals -4.3.
