Answer 1

Answer:

Step-by-step explanation:

-15

Answer 2

Answer: -15

Step-by-step explanation:

a=-60,  d=+15

so a4=  a+(n-1)d

    a4=  a+3d

    a4= -60+3(15)

    a4= -60+ 45

Hence, a4= -15

              or

we can clearly see the pattern is increasing in the order of 15 every next no. so the next no would be -30 + 15= -15.
