Assuming that the equation is 4.7x+3.8=13.2:
4.7x=9.4 - isolate x on one side
x=2 - divide 9.4/4.7 to solve for x
The answer is C.
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.
