Answer:
the sequence is 2, 14, 98, 686.
Explanation:
As we know in any geometric sequence the terms are denoted by
![T_(n)=a(r)^(n-1)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/8uogtn2rxh6z0pz1gxw2p1cvfi6r80di2p.png)
We have to find the first four terms of geometric sequence which has first term a = 2 and common ratio of the terms r = 7
number of terms = 4
The sequence from the formula will be
![2, 2.7, 2.(7)^(2),2.(7)^(3)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/aah79klyb9iy7sirsdk9jvf78h4a37oexm.png)
or the sequence is 2, 14, 98, 686.
