Question

Find the eleventh term sequence:

1.95, 2.85, 3.75, 4.65....
a) 11.85
b) 10.95
c) 10
d) 12.75

Answer 1

b). 11.85

Explanation:

The rule is add 0.9

1.95 + 0.9 = 2.85

2.85 + 0.9 = 3.75

3.75 + 0.9 = 4.65...

if you were to add 7 more times you will get to 11.85.

*Here's a trick to make it shorter*

11 × 0.9 = 9.9

9.9 + 1.95 = 11.85

hopefully this helped :3
