Question

plz solve this step by step​

Answer 1

Answer:

-672, -492, -312, -132, 48, 408.......

Step-by-step explanation:

a+4d=48 ...........( I)

a+8d=768 ..........( II)

subtract equation (I) from (II)

4d= 720

d= 720/ 4

d= 144

now putting the value of 'd' in equ. (II)

a+4*180=48

a=48-720

a= -672 , d=180

a1= -672

a2= a+d = -672+180 = -492

a3= a+2d= -672+2*180= -312

a4= a+3d= -672+3*180= -132

a5= a+4d= -672+4*180= 48

a6= a+5d= -672+5*180= 408
