A1=2
a2=-8
a3=32
a4=-128
a2/a1=(-8)/2→a2/a1=-4
a3/a2=32/(-8)→a3/a2=-4
a4/a3=(-128)/32→a4/a3=-4
a2/a1=a3/a2=a4/a3=r=-4
an=a1*r^(n-1)
an=2*(-4)^(n-1)
The explicit rule for the nth term of the given sequence is an=2*(-4)^(n-1)
Answer:
(0-,10) (1,-6)
Step-by-step explanation:
because the slope is 4 and the y intercept is 10
In total there are 5 kids so
5÷3.5=1.4
(rounded)
I'm pretty sure this is correct
