Question

find the first five terms of this sequence a1=a2=2,An=an-1-3,n>2​

Answer 1

Step-by-step explanation:

   By putting n = 3, 4, 5, 6, 7 we get next five term of the sequence

   a3 = a2 – 3 = 2 – 3 = -1

   a4 = a3 – 3 = -1 – 3 = -4

   a5 = a4 – 3 = -4 – 3 = -7

   a6 = a5 – 3 = -7 – 3 = -10

   a7 = a6 – 3 = -10 – 3 = -13

   ∴ The next five terms are -1, -4, -7, -10, -13

Answer 2

Step-by-step explanation:

put value of n in different equation. n.1 .n.2 .n.3
