the first term of a sequence of numbers is 24.
the term-to-term rule of this sequence is to 'add 8'
josie says
"No number in this sequence is in the five times table"
give an answer to show she's wrong.
is 85 a number in this sequence?
24 + 8*2 = 40 = 8*5
all numbers will be even (24+8n) so 85 cannot be in the sequence.
Well, Josie, clearly you haven't done your math homework. Let me enlighten you: the sequence starts with 24, and the term-to-term rule is to add 8. So, if we follow this rule, the second term would be 32, the third term 40, the fourth term 48, and so on. Now, 85 is NOT in the five times table, as 85 divided by 5 gives us a lovely decimal number. Therefore, 85 is NOT a number in this sequence. Sorry, Josie, but you're still in need of some mathematical clowning around!
To determine whether 85 is a number in this sequence, we can use the given information. According to the term-to-term rule of the sequence, we start with the first term, which is 24, and then add 8 to each term.
To find out if 85 is a term in this sequence, we can work backward by subtracting 8 repeatedly from 85 until we reach a number that is present in the sequence:
85 - 8 = 77
77 - 8 = 69
69 - 8 = 61
61 - 8 = 53
53 - 8 = 45
45 - 8 = 37
37 - 8 = 29
29 - 8 = 21
21 - 8 = 13
13 - 8 = 5
5 is now in the sequence, so it follows that 85 is also in the sequence since we obtained it through the process described above.
Therefore, Josie is wrong in saying that no number in the sequence is in the five times table as 85 is a number in this sequence.
To determine if 85 is a number in the given sequence, we can apply the term-to-term rule which is to "add 8" to each term.
To find the subsequent terms in the sequence, we start with the first term, which is 24, and add 8 repeatedly.
24 + 8 = 32
32 + 8 = 40
40 + 8 = 48
48 + 8 = 56
Continuing this pattern, we can see that the sequence consists of the following numbers: 24, 32, 40, 48, 56, ...
Based on this sequence, it is clear that 85 is not a number in the given sequence, as it does not appear in the list above. Therefore, Josie is correct in saying that 85 is not present in the sequence.
