Question

Sequence B: consider the sequence 1.5,3,6,12

Answer 1

n x 2 = x

Explanation:

This is the answer because:

1) 1.5 x 2 = 3

2) 3 x 2 = 6

3) 6 x 2 = 12

Therefore, the pattern in this sequence is n x 2 = x

Hope this helps!

Answer 2

Use the formula

a n = a 1 r n − 1

to identify the geometric sequence.

a n = 1.5 ⋅ 2 n − 1
