Write the first five terms of each of the sequences in Questions 1 to 6 whose nth terms are :
`a_(n)=n(n+2)`

Text Solution

Verified by Experts

The correct Answer is:
N/a
nth term of given sequence `a_(n)=n(n+2)`
`therefore" 1st term of given sequence "a_(1)=1(1+2)=1xx3=3,`
`therefore" 2nd term of given sequence "a_(2)=2(2+2)=2xx4=8,`
`therefore" 3rd term of given sequence "a_(3)=3(3+2)=3xx5=15,`
`therefore" 4th term of given sequence "a_(4)=4(4+2)=4xx6=24,`
`therefore" 5th term of given sequence "a_(5)=5(5+2)=5xx7=35,`
Therefore, first 5 terms of given sequence are
`a_(1)=3,a_(2)=8,a_(3)=15,a_(4)=24,a_(5)=35.`
