Is 100 a term of arithmetic sequence 21.32.43? What about 1000?
Answers
Answer:
we are interested in the first number in this sequence greater than 1000. Since n must be an integer, the first term that is > 1000 will be n = 201.
Step-by-step explanation:
so, 43rd term is 96.
The 'nth' term is a formula with 'n' in it which enables you to find any term of a sequence without having to go up from one term to the next. 'n' stands for the term number so to find the 50th term we would just substitute 50 in the formula in place of 'n'.
The fifth term is just the next term. One possible answer can be obtained by looking at the differences in the first four terms: 2 (=3–1), 4 (=7–3) and 8 (=15–7). They are 2^1, 2^2 and 2^3. I would say the fifth term is 15+2^4 = 15 + 16 = 31.
Which of the following is the first term greater than 100? The forty-first term is the correct response.
