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:
one solution
Step-by-step explanation:
3x-1=3
Add 1 to each side
3x-1+1=3+1
3x = 4
Divide by 3
3x/3 = 4/3
x = 4/3
There is one solution
Answer:
Time= 4 years
Step-by-step explanation:
Giving the following information:
Principal (P)= $12,000
Interest rate (r)= 10% = 0.10
Interest earned (I)= $4,800
<u>To calculate the time required to gain $4,800 interest, we need to use the following formula:</u>
T= I / (P*r)
T= 4,800/(12,000*0.1)
T= 4 years
Answer:
45.7%
Step-by-step explanation:
12 + 7 + 16 = 35
16/35 = 0.457 = 45.7%
