Answer:
70,000
2.5 million
12 million
20.8 million
29.3 million
53.5 million
Step-by-step explanation:
Three and a half divided by seven-eighth equals seven over two times eight over seven equals fifty over fourteen equals four
A(n) = current term
a(n + 1) = next term
in a geometric sequence, the next term comes from a product of the current term and the common ratio.
the common ratio can be any value, let's say use r = ½.
if the current term is say hmmm 40, the next term is 40*½ , or 20, so indeed, the next term is smaller.
(-9)+(-6)+(-4)+(-1) is the expression and (-20) is the sum
