Answer:
The missing term is either +14 or -14
Step-by-step explanation:
The missing term can be found by
Let the term be x
x/2 = r the common ratio
98/x = r
x/2 = 98/x
Using cross products
x^2 = 2*98
x^2 =196
Taking the square root of each side
sqrt(x^2) = sqrt(196)
x = ±14
The missing term is either +14 or -14
The ratio is either +7 or -7
