Answer» Answer: Multiple of 7 = 7 , 14 , 21 ........ 3 added = 10 , 17 , 24 ........ an = a + (n - 1) d an = 10 + (n - 1) 7 an = 10 + 7n - 7 an = 7n + 3 Let 2000 be nth term of A.P. an = a + (n - 1) d 2000 = 10 + (n - 1) 7 2000 = 10 + 7n - 7 2000 = 7n + 3 7n = 1997 n = 1997/7 (n ≠ whole number) Hence, 2000 is not a term of A.P.
