If i know a5 = -48 and r = 2 in a geometric sequence, how do i find the 8th term and explicit formula? how can i calculate a1?

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
