Answer :

Formula Used.

a_{n} = a + (n–1)d

If a = 100, d = –7

Then a_{1} = a + (n–1)d = 100 + (1–1)(–7) = 100

a_{2} = a + (n–1)d = 100 + (2–1)(–7) = 100 + (–7)×1 = 93

a_{3} = a + (n–1)d = 100 + (3–1)(–7) = 100 + (–7)×2 = 86

a_{4} = a + (n–1)d = 100 + (4–1)(–7) = 100 + (–7)×3 = 79

a_{n} = a + (n–1)d = 100 + (n–1)(–7) = 107 – 7n

∴ The A.P is 100, 93, 86, 79……107–7n
