10, 7, 4, 1, −2, −5
Responses
a1 = 10; an = an −1 + 3
a1 = 10; an = an −1 + 3
a1 = −3; an = an −1 +10
a1 = −3; an = an −1 +10
a1 = −3; an = a10 + 3
a1 = −3; an = a10 + 3
a1 = 10; an = an −1 − 3
a1 = 10; an = an −1 - 3
To find the correct recursive formula for the given sequence, we need to observe the pattern in the sequence.
The sequence is: 10, 7, 4, 1, -2, -5
By observing the given sequence, we can see that each term is obtained by subtracting 3 from the previous term.
Therefore, the correct recursive formula for the sequence is:
a1 = 10; an = an-1 - 3
So, the correct answer is:
a1 = 10; an = an-1 - 3
The correct recursive formula for the sequence 10, 7, 4, 1, -2, -5 is:
a1 = 10; an = an - 1 - 3
