Problema Solution
The first term of a sequence of numbers is -8. Each term after the first is obtained by multiplying the preceding term by -1 and then adding 3. What is the 100th term of the sequence?
How would I set this expression up to solve for any nth term?
Answer provided by our tutors
2nd term will be = (-8)*(-1) + 3 =11
3rd tem will be = 11*(-1) + 3 = -8
again 4th term will be = (-8)*(-1) + 3 = 11
thus even terms are same and odd terms are same
100th term will be = 11
nth term = -8 if n is odd or 11 if n is even
