Hi,
*Note: For an Arithmetic progression {{{a[n] = a[1] + (n-1)d}}}  
1. Find the 20th term of the following sequence.
-6, -4, -2, 0, ... 
{{{a[20] = -6 + 19*2 = highlight(32)}}}
2. What is the next term for the given arithmetic sequence?
-3, -2.25, -1.5, -0.75, ... 
{{{a[5] = -3 + 4*.75 = highlight(0)}}}
3. Find the common difference for the sequence shown.{{{highlight(-7)}}}
56, 49, 42, 35, ... 
4. The first term of an arithmetic sequence is -3 and the fifteenth term is 53. What is the common difference of the sequence?
{{{a[n] = a[1] + (n-1)d}}} 
53 = -3 + 14*d  {{{d = highlight(4)}}}
5. Which of the following is an arithmetic sequence?  {{{d=highlight(2)}}}
0, 2, 4, 6, ...
6. Which of the following equations could be used to solve for the tenth term of the following sequence ? 15, 13, 11, 9, ...
{{{a[10] = 15 + 9*2}}} 
7. Find the common difference for the given sequence. {{{d=highlight(.05)}}}
1.05, 1.1, 1.15, 1.2, ...
8. Find the common difference of the arithmetic sequence shown.{{{d=highlight(1/8)}}}
1/4,3/8,1/2
