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.

Answer:
x=-7
Step-by-step explanation:
9x + 16 = 4x - 19
Subtract 4x from each side
9x-4x + 16 = 4x-4x - 19
5x+16 = -19
Subtract 16 from each side
5x+16 -16 = -19-16
5x = -35
Divide each side by 5
5x/5 = -35/5
x = -7
