Step-by-step explanation:
d=(3/4)-(1/4)=(5/4)-(3/4)=(7/4)-(5/4)=1/2
 then it is an arithmetic sequence
by using this equation :
a(n) = a1 +(n-1)d
and we have : a1=(1/4),  d=(1/2)
So:
Explicit formula: a(n) = (1/4) +(n-1)*(1/2)

-6
You would divide -4.3 on both sides. Since -4.3 divided by itself equals 1 the g will be isolated. So the answer would be -6 because 25.8 divided by -4.3 is -6.
