Answer:

137,774

Step-by-step explanation:

The terms are going by x3.

term 1: 14

term 2: 14 x 3 = 42

term 3: 42 x 3 = 126

term 4: 126 x 3 = 378

term 5: 378 x 3 = 1,134

term 6: 1,134 x 3 = 3,402

term 7: 3,402 x 3 = 10,206

term 8: 10,206 x 3 = 30,618

term 9: 30,618 x 3 = 91,854

Now add all of the terms together:

14 + 42 + 126 + 378 + 1,134 + 3,402 + 10,206 + 30,618 + 91,854 = 137,774
