First five term for An=n^2-2n
densk [106]

First 5 terms are: -1,0,3,8,15

Step-by-step explanation:

we will put n=1,2,3,4,5 to find first 5 terms of the sequence

Explicit formula for sequence is:

a_n = n^2-2n

Putting n=1

a_1 = (1)^2-2(1)\\= 1-2\\= -1

Putting n=2

a_2 = (2)^2-2(2)\\= 4 - 4 \\=0

Putting n=3

a_3 = (3)^2-2(3)\\= 9-6\\= 3

Putting n=4

a_4 = (4)^2 - 2(4)\\= 16-8 \\= 8

Putting n=5

a_5 = (5)^2-2(5)\\= 25 - 10\\= 15

Hence,

First 5 terms are: -1,0,3,8,15
