Answer:
A) The first 4 terms of the sequences are: , , and .
B) An explicit formula for this sequence can be written as:
C) A recursive formula for this sequence can be written as:
Step-by-step explanation:
A) You can find the firs terms of this sequence simply selecting an odd integer and summing the consecutive 3 ones:
(a.1)
B) Observe the sequence of odd numbers 1, 3, 5, 7, 9, 11, 13(...).
You can express this sequence as:
(b.1)
If you merge the expression b.1 in a.1, you obtain the explicit formula of the sequence:
(a.1)
(b.2)
(b.3)
(b.s)
C) The recursive formula has to be written considering an initial term and an N term linked with the previous term. You can see an addition of 8 between a term and the next one. So you can express each term as an addition of 8 with the previous one. Therefore, if the first term is 16:
(c.s)
X is 149°. I hope this helps!

Answer:
2.5 hours
Step-by-step explanation:
Answer:
1.44 pounds
Step-by-step explanation:
From the above question, we are told that:
The shop has 3 for 2 offer on chocolate bars going on .This means a customer can buy 2 chocolates get 1 free, for the price of 2 chocolates, a customer can get 3 chocolates.
If the price of 1 chocolate bar = 72p
2 chocolate bars =
72p × 2
= 144p
Hence, Sian spends 144p
We are asked to convert our answer to pounds
The symbol p represent pence in money form
Hence,
100p(pence) = 1 pound
144p(pence) = x
100p × x = 144p × 1
x = 144p/100p
x = 1.44 pounds
Therefore, Sian spends 1.44 pounds
