Answer:
Net_change_in_depth = 450/7 ft = 64 2/7 ft
Step-by-step explanation:
Missing info attached below
Depth_of_the_frequency_signal = -180 4/7 ft = -1264/7 ft
Depth_of_the_submarine = -116 2/7 ft = -814/7 ft
Net_change_in_depth =
Depth_of_the_submarine - Depth_of_the_frequency_signal
Net_change_in_depth = -814/7 ft - (-1264/7 ft)
Net_change_in_depth = 450/7 ft = 64 2/7 ft

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
