Answer 1

Answer:

883 is the final answer of this question

Answer 2

a= -8

d= 11

let,the x term of AP be 143 more than 69th term

$t_x=143+t_{69}$

we know,

$t_n=a+(n-1)d\\t_{69}=(-8)+(68)11\\t_{69}=740\\\\t_x=a+(x-1)d\\\\143+740=(-8)+(x-1)11\\\\891=11x-11\\\\902=11x\\\\x=\frac{902}{11}\\\\\underline{x=82}$

89th term of A.P will be 143 more than the 69th term of given A.P
