Answer 2

$\large{\underline{\bf{\pink{Given:-}}}}$

✦ First term = 117.

✦ common difference :- 104 -117 = -13

$\large{\underline{\bf{\pink{To\:Find:-}}}}$

✦ we need to find the 8th term .

$\huge{\underline{\bf{\red{Solution:-}}}}$

$\rm\:a_n = a + (n-1)d\:$

$\longmapsto \rm\:\:a_8= 117+ (8-1)-13$

$\longmapsto \rm\:\:a_8=117+7(-13)$

$\longmapsto \rm\:\:a_8=117-91$

$\longmapsto \rm\:\:a-8=26$
