# Arithmetic Sequences Examples

### Example 1

 Write the first four terms of the arithmetic sequence with a1 = 4 and d = 5.

### Example 2

 If a1 = 3 and d = 5, find a5.

### Example 3

 If a1 = 12 and d = -2, find a11.

### Example 4

 An arithmetic sequence has a5 = 11 and a6 = 13. Find a1 and d.

### Example 5

 An arithmetic sequence has a10 = 52 and a11 = 56. Find a1 and d.

### Example 6

 Find a1 and d for the arithmetic sequence with a2 = 8 and a4 = 28

### Example 7

 Find a1 and d for the arithmetic sequence with a50 = 14 and a100 = -136.
