Answer 1

Answer 2

Answer:

• what is the 20th term of the sequence defind by an=(n-1)(2-n)(3+n)

Step-by-step explanation:

we need to find 20th term I,e a20

let an=(n-1)(2-n)(3+n). ...1

putting n=20 in ( 1 )

a20 = (20-1) (2-20) ( 3+ 20 )

= (19) x (-18 ) x (23)

= -7866

HENCE THE 20TH TERM IS -7866

hope it helps
