Given the sequence 7, 14, 28, 56, which expression shown would give the tenth term? 7^10 7 • 2^10 7 • 2^9

7•2^10

Step-by-step explanation:

First step would be to find the tenth term so 56•2=112, 112•2=224, 224•2=448, 448•2=896, 896•2=1,792, 1,792•2=3,594, 3,594•2=7,168. The tenth term is 7,168.

Then, Solve each expression

1.7^10=282,475,248

2. 7•2^10=7,168

3.7•2^9=3,584

Finally, decide which one matches the 10th term which is expression number 2 7•2^10
