HEY

HERE IS ANSWER


Question:

which term of the AP:121,117,113,...........,is its first negative term.

Given.

a1= 121.

a2=117.

hence

d= a2-a1

= 121-117

=-4

hence

an=a+(n-1)d

0> 121+ (n-1)-4

0>121+(-4n)+4

0>125-4n.

0>-125=-4n

0>-125/-4=n

n=31.5

n= 32th term.


Hope it helps

thanks
