Answer 2

There are 23 plants in the first row, 21 plants in the second row, 19 plants in the third row, in a backyard. The plants in the last row are wilted.

The sequence's A.P. is 23,21,1,  a=23, d=2, n=10

So, as we know, t n =a+(n1)d t n =23+(101)(2) t n =23+(9)(2) t n =2318 t n =5

In the last row, there are five plants.

If the nth row's last phrase is

S=1+5+11+19

T (n) n  terms

T (n)" terms  0=1+4+6+8  terms - T (n) terms -T (n)  terms -T (n) terms

T (n)=1+2(2+3+4=1+2((n-1))/(2)

[2*2+(n-2)*1] =1+(n+1)(n+2) =1+n^(2)+n-2

T (n) = n(2)+n-1 implies T (n)= T (n)= T (n)= T (n

T (60)=(60)(2)+60-1=3600+59=3659 T (60)=(60)(2)+60-1=3600+59=3659
