Concept Review 1: Sequences
- What is a sequence?
- If the pattern of a sequence repeats every six terms, how do you determine the 115th term of the sequence?
- If the pattern of a number sequence repeats every four terms, how do you find the sum of the first 32 terms
of the sequence? - If a number sequence repeats every five terms, how do you determine how many of the first 36 terms are
negative? - What is the 30th term of the following sequence?
, 1, 3, 9,...- The first term in a sequence is 4, and each subsequent term is eight more than twice the preceding term.
What is the value of the sixth term? - The word SCORE is written 200 times in a row on a piece of paper. How many of the first 143 letters are
vowels? - The third term of a sequence is x.If each term in the sequence except the first is found by subtracting 3 from
the previous term and dividing that difference by 2, what is the first term of the sequence in terms of x? - A 60-digit number is created by writing all the positive integers in succession beginning with 1. What is the
