Answer:
Sequence will be 2, 14, 98, 686.
Step-by-step explanation:
Since we know in an geometric sequence the terms are in the form are
in which
a = first term
r = common ratio
n = number of term
Now from this expression we can all terms of the sequence
in which a = 2 and common ratio r = 7
The sequence will be

Or 2, 14, 98, 686
So the answer is 2, 14, 98, 686.
Sin C= 3/5
Your answer would be A
