The slope of a line is -3. Find the slope of a line that is perpendicular to this line.
Find the 30th term of the following sequence.
2, 8, 14, 20, ...
They are both arithmetic sequences. Here's the formula: An = A + (n-1)d... An is just the value of the nth term, A is the first term, n is the nth term and d is the common difference. [ A=2 n=30 d=(8-2)= 6 So, An = 2 + (30-1)6 = 176
