Find the nth term of the AP 8, 3, –2, –7, –12, …. |
Answer» To Find: nth term of the AP Given: The series is 8, 3, –2, –7, –12, …. a1 = 8, a2 = 3 and d = 3–8 = –5 (Where a = a1 is first term, a2 is second term, an is nth term and d is common difference of given AP) Formula Used: an = a + (n - 1)d an = a1 + (n - 1)(–5) = 8 – (5n – 5) = 8 – 5n + 5 = 13 – 5n So the nth term of AP is equal to 13 – 5n |
