Answer 2

First-term 4

First-term 4Second-term 9 = 4 X 2 + 1 = 8 + 1

First-term 4Second-term 9 = 4 X 2 + 1 = 8 + 1Third-term , 29 = 9 X 3 + 2 = 27 + 2

First-term 4Second-term 9 = 4 X 2 + 1 = 8 + 1Third-term , 29 = 9 X 3 + 2 = 27 + 2Fourth-term , 119 = 2 9 X 4 + 3 = 116 + 3

First-term 4Second-term 9 = 4 X 2 + 1 = 8 + 1Third-term , 29 = 9 X 3 + 2 = 27 + 2Fourth-term , 119 = 2 9 X 4 + 3 = 116 + 3Fifth-term , 599 = 11 9 X 5 + 4 = 595 + 4

First-term 4Second-term 9 = 4 X 2 + 1 = 8 + 1Third-term , 29 = 9 X 3 + 2 = 27 + 2Fourth-term , 119 = 2 9 X 4 + 3 = 116 + 3Fifth-term , 599 = 11 9 X 5 + 4 = 595 + 4Sixth-term , 3599 = 599 X 6 + 5 = 3594 + 5

First-term 4Second-term 9 = 4 X 2 + 1 = 8 + 1Third-term , 29 = 9 X 3 + 2 = 27 + 2Fourth-term , 119 = 2 9 X 4 + 3 = 116 + 3Fifth-term , 599 = 11 9 X 5 + 4 = 595 + 4Sixth-term , 3599 = 599 X 6 + 5 = 3594 + 5Seventh-term , 25119 = 3599 X 7 + 6 = 25193 + 6

First-term 4Second-term 9 = 4 X 2 + 1 = 8 + 1Third-term , 29 = 9 X 3 + 2 = 27 + 2Fourth-term , 119 = 2 9 X 4 + 3 = 116 + 3Fifth-term , 599 = 11 9 X 5 + 4 = 595 + 4Sixth-term , 3599 = 599 X 6 + 5 = 3594 + 5Seventh-term , 25119 = 3599 X 7 + 6 = 25193 + 6EighthSeventh-term , 201599 = 25119 X 8 + 7 = 201592 + 7

First-term 4Second-term 9 = 4 X 2 + 1 = 8 + 1Third-term , 29 = 9 X 3 + 2 = 27 + 2Fourth-term , 119 = 2 9 X 4 + 3 = 116 + 3Fifth-term , 599 = 11 9 X 5 + 4 = 595 + 4Sixth-term , 3599 = 599 X 6 + 5 = 3594 + 5Seventh-term , 25119 = 3599 X 7 + 6 = 25193 + 6EighthSeventh-term , 201599 = 25119 X 8 + 7 = 201592 + 7So series becomes;

First-term 4Second-term 9 = 4 X 2 + 1 = 8 + 1Third-term , 29 = 9 X 3 + 2 = 27 + 2Fourth-term , 119 = 2 9 X 4 + 3 = 116 + 3Fifth-term , 599 = 11 9 X 5 + 4 = 595 + 4Sixth-term , 3599 = 599 X 6 + 5 = 3594 + 5Seventh-term , 25119 = 3599 X 7 + 6 = 25193 + 6EighthSeventh-term , 201599 = 25119 X 8 + 7 = 201592 + 7So series becomes;4 , 9 , 29 , 119 , 599,3599 . 25119.201599
