Question

n^2 + 20 find first 3 terms?

Answer 1

Let a series of integers is represented by the equation: n^2 + 20

Therefore, to calculate three terms of this series n should be equal to1, 2 and 3 respectively.

So,

1st term = n^2 + 20 = 1^2 + 20 = 21

2nd term = 2^2 + 20 = 4 + 20 = 24

3rd term = 3^2 + 20 = 9 + 20 = 29

Answer 2

let n=0,1,2

n=0

=0^3+30

=0+20

=20

n=1

=1^2+20

=1+20

=21

n=2

=2^2+20

=4+20

=24

therefore , the first 3terms are 20,21,24
