Find the 9th term of geometric sequence 7,14,28, ...

56

Step-by-step explanation:

We have to look for the pattern in the numbers, so we can figure out what the next term in the sequence is!

It looks like, each number is multiplied by 2!

7 * 2 = 14

14 * 2 = 28

So,

28 * 2 = ?

The next term in the geometric sequence is ... 56!

Answer: a^9=1792

Step-by-step explanation:

To find a9 we use formula

an = a1 · r

n-1

an = a1 · r

n-1

a9 = 7 · 2

9-1

a9 = 7 · 256

a9 = 1792
