The explicit rule for given sequence is:
Further explanation:
We have to determine first of all if the sequence is arithmetic or geometric.
- If the difference of two consecutive terms is same then the sequence is arithmetic sequence
- If the ratio of two consecutive terms is same then the sequence is geometric sequence
Given sequence is:
12,22,32,42
The common difference is 10 which is same for all consecutive terms. So the sequence is an arithmetic sequence.
The general formula for arithmetic sequence is:
Putting the values of a1 and d

sin(0) = opposite/hypotenuse = 2/5
cos(0) = adjacent/hypotenuse = sqrt21/5
tan(0) = opposite/adjacent = 2/sqrt21 * sqrt21/sqrt21 = 2sqrt21/21
cot(0) = adjacent/opposite = sqrt21/2
sec(0) = hypotenuse/adjacent = 5sqrt21/21
