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:
The tree is about 8 feet.
Step-by-step explanation:
7 2/3 = 7.6 as a fraction.
30 1/5 = 30.5 as a fraction.
Know, we must divide 30.5 by 7.6.
30.5 ÷ 7.6 = 4 when rounded to the nearest whole number.
Since we know that the stake is 2 feet, we must multiply this by 4, since the other shadow is 4 times the amount of the stake.
2 x 4 = 8
This means the tree is about 8 feet.
The next two numbers are 20, -4
