Answer 1

Answer:

-3 is the first negative term.

Step-by-step explanation:

step1)we know that An=A+(n-1)d

step2) here they gave A as 45 and d=a1-a2⇒45-41=4

step3)now take the 10th term A10 as A+9d=45-36=9 and take the 12 th term=A=12d=45-48=-3

step4)hence the 12term is the first negative term of the series
