Answer: 28

Step-by-step explanation:

The 7th term of an AP is 4 and its common difference is -4. The 7th term of an arithmetic progression is written as:

a + 6d = 4

where,

a = first term

d = common difference= -4

a + 6d = 4

a + 6(-4) = 4

a - 24 = 4

a = 4 + 24

a = 28

The first term is 28.
