Question at position 6
A sequence can be generated by using an=a(n-1)+4. If a1=2, what is the value of a20?
answer all questions
To find the nth term of the sequence -20, -23, -26, -29,... we use the equation an = -20 - 3(n-1), so the correct answer is an = -20 - 3n.
For the sequence -10, 20, -40, 80,... the formula to find the nth term is an = -10 * (-2)^(n-1).
If a sequence is generated by an = a(n-1) - 0.5 and a1 = 16, to find a45 we need to keep applying the formula.
For a sequence where a2=9, a3=7, and a4=5, the equation to find the nth term is an = 11 - 2(n-1).
For the sequence a1= 4, a2= 16, a3= 64, the formula to find the nth term is an = 4 * 4^(n-1).
If a sequence is generated by an = a(n-1) + 4 and a1 = 2, to find a20 we need to keep applying the formula.
what are the answers to 3 4 and 6
For question 3, with the sequence formula an = a(n-1) - 0.5 and a1 = 16, we can find a45 using the formula.
a45 = a44 - 0.5
a44 = a43 - 0.5
...
a2 = a1 - 0.5
Since a1 = 16, we can calculate a2, a3, a4, ..., a45 step by step until we reach a45.
For question 4, with the given values a2=9, a3=7, and a4=5, we can see the pattern that the nth term decreases by 2 each time. The formula would be:
an = 11 - 2(n-1)
And for question 6, if a sequence is generated by an = a(n-1) + 4 and a1 = 2, to find a20 we need to keep applying the formula.
