Step-by-step explanation:
To obtain a term in the sequence add the previous 2 terms, that is
= + ← in general terms
(a)
Given 1 4 5 9 14
Then the next 2 terms are 9 + 14 = 23 and 23 + 14 = 37
(b)
Given a₄ = 30 and a₅ = 49 , then
a₃ = 49 - 30 = 19
a₂ = 30 - 19 = 11
a₁ = 19 - 11 = 8
Sequence is 8 11 19 30 49 ....
(c)
Given a₂ = x and a₃ = y , then
a₁ = y - x
a₄ = a₃ + a₂ = y + x
a₅ = a₄ + a₃ = y + x + y = 2y + x
Answer:
-n + 373
Step-by-step explanation:

To find how much each half gallon jug weighs, you do : 125.1 divided by 30 and you get 4.17
so now multiply 4.17 * 110 to get 458.7 pounds
So 110 half gallon jugs weigh 458.7 pounds
Hope This Helps :)
