Question

Determine ap whose third term is sixteen and the difference of fifth from seventh term is 12

Answer 1

Answer:

The Arithmetic Progressive is, 4, 10, 16, 22, 28, ...

Explanation:

In an A.P

t3 = a + 2d = 16 ->> (1)

t7 - t5 = a + 6d - a - 4d = 12

2d = 12

d = 6 ->> (2)

Sub (2) in (1),

a + 12 = 16

a = 4

With a = 4, d = 6, The A.P can be determined as

4, 10, 16, 22, 28, ...
