Question

I really need help please

Answer 1

`\sf\\b.\ Given:\\\textsf{nth term}(t_n)=6n+3\\\textsf{So,}\\\textsf{First term}(t_1)=6(1)+3=9\\\textsf{Second term}(t_2)=6(2)+3=15\\\textsf{Third term}(t_3)=6(3)+3=21\\\textsf{Fourth term}(t_4)=6(4)+3=27\\\textsf{Fifth term}(t_5)=6(5)+3=33`

`\sf\\\textsf{c. Given:}\\\textsf{nth term}(t_n)=10^n-7\\\textsf{Now,}\\\textsf{First term}(t_1)=10^1-7=3\\\textsf{Second term}(t_2)=10^2-7=93\\\textsf{Third term}(t_3)=10^3-7=993\\\textsf{Fourth term}(t_4)=10^4-7=9993\\\textsf{Fifth term}(t_5)=10^5-7=99993`

`\sf\\\textsf{d. Here,}\\\textsf{nth term}(t_n)=2n-1\\Now,\\\textsf{1st term}(t_1)=2(1)-1=1\\\textsf{2nd term}(t_2)=2(2)-1=3\\\textsf{3rd term}(t_3)=2(3)-1=5\\\textsf{4th term}(t_4)=2(4)-1=7\\\textsf{5th term}(t_5)=2(5)-1=9`
