n= 32nd term
i hope it helps ^_^
Answer:
32 TERM.
Step-by-step explanation:
NOW ,
REMEMBER THAT : aₙ= a + (n - 1)d.
NOW , FROM THE A.P : a= 121 and d= -4.
AS WE ARE FINDING FIRST NEGETIVE TERM , IT WILL BE LESS THAN 0.
SO,
LET THE FIRST NEGETIVE TERM BE aₙ= a + (n - 1)d , SO
aₙ < 0
a + (n - 1)d < 0
121 -4n + 4 <0
4n>125
n>31¹₄
NOW , AS n IS GREATER THAN 31¹₄ , IT WILL BE THE NEXT GREATER NUMBER OR ,
n = 32 term.
