An=a1(r^(n-1))=1(r^(n-1))=r^(n-1)domanim means of which numbers can be usenormally you can say "first term, second term, etc", so it is all the integers from 1 of them and above itintegers >1A is answer24-3(4^(n-1))evalueate each of the one or the use of the sum of the function calculator-3(4^(1-1))=-3-3(4^(2-1))=-12-3(4^(3-1))=-48-3(4^(4-1))=-192-3(4^(5-1))=-768add them-3-12-48-192-768=-1023A is answer23.
