New grass seeds grow rapidly. A grass seed has grown to 12 millimeters tall. Tomorrow it will be 23 inches tall, the next day it will be 34 inches tall, and on the next day it will be 45 inches tall. Write a rule to represent the height of the bean plant as an arithmetic sequence. How tall will the plant be in 15 days?

A. a(n)=16+(n-1)11; 194 millimeters

B. a(n)=12+(n-1)11; 166 millimeters

C. a(n)=13n; 195 millimeters

D. a(n)=12n; 180 millimeters

Respuesta :

The answer is B. a(n)=12+(n-1)11; 166 millimeters
12 --> 23 = add 11
23 --> 34 = add 11
34 --> 45 = add 11

The arithmetic sequence is add 11. 

11 (15) = 165 mm
It starts at 12, so add 1, which is 166. 

So it is B. 

Hope this helps! I am sorry if this is wrong, but I tried!
