Question

4, 6, 9, ... find the 7th term.

Answer 1

13.5 is the next term

4, 6, 9, 13.5

Explanation:

This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 3/2

formula= an=a1⋅r^n-1

Answer 2

45.5625

Explanation:

The pattern seems to be x + (x/2) = y where x is the previous number and y is the next number.

4 + (4/2) = 6

6 + (6/2) = 9

therefore we continue the pattern. In doing so we get:

30.375 + (30.375/2) = 45.5625
