Question

A gardener buys a plant that is 12cm in height. Each week after that the plant grows 10cm. Note: The plant is 12cm high at the beginning of the week.

what is the formula and value for t10 and t12 in an arithmetic sequence????

Answer 1

formula = height = 12+10t

where t = number of weeks

so for t10

 height = 12+10(10) = 12+100 = 112 cm

for t12

height = 12+10(12) = 12 +120 = 132 cm
