Given that the recursive formula for a sequence is
The first term of the sequence is
We need to determine the first four terms of the sequence.
<u>Second term:</u>
The second term of the sequence can be determined by substituting n = 2 in the recursive formula.
Thus, we have;
Thus, the second term of the sequence is 8.
<u>Third term:</u>
The third term of the sequence can be determined by substituting n = 3 in the recursive formula.
Thus, we have;
Thus, the third term of the sequence is 14.
<u>Fourth term:</u>
The fourth term of the sequence can be determined by substituting n = 4 in the recursive formula.
Thus, we have;
Thus, the fourth term of the sequence is 22.
Hence, the first four terms of the sequence is 4, 8, 14, 22.
Answer:
i) 75.8
ii) 997,002
Step-by-step explanation:
Each of these expressions can be rewritten to make evaluation a little easier.
<h3>i)</h3>
The difference of squares can be factored.
a^2 -b^2 = (a -b)(a +b)
8.79^2 -1.21^2 = (8.79 -1.21)(8.79 +1.21) = (7.58)(10) = 75.8
__
<h3>ii)</h3>
The values are near 1000, so can be expressed as differences from that number.
(999)(998) = (1000 -1)(1000 -2) = 1000^2 -3(1000) +2) = 997,002
Answer:
no
Step-by-step explanation:
11/4 plus 11/4 is 22/4
to make this a whole number and a fraction we subtract 4 from the 22 as many times as we can. we can do this 5 times, with 2 left over.
the answer is 5 2/4, which you can simplify to 5 and a half
Answer:
You distribute the 2 to the m=2m
Then you distribute the 2 to the 11 which gives you 22
ANSWER: 2m+22
