Answer:
= 103 - 3n
Step-by-step explanation:
there is a common difference between consecutive terms , that is
97 - 100 = 94 - 97 = 91 - 94 = - 3
This indicates the sequence is arithmetic with explicit equation
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 100 and d = - 3 , then
= 100 - 3(n - 1) = 100 - 3n + 3 = 103 - 3n
First term = 2(1) - 3 = 2 - 3 = -1
Answer:
Step-by-step explanation:
The ratio of new length 7 to the initial length 19 is 2.7
Therefore new width will be 2.7×4 which will be 10.9 or about 11 inches
