I need help with this.
in a set of four numbers, the first three are in a geometric sequence and the last in an arithmetic sequence with a common difference of 6. if the number is the same as the fourth, find the four...
the sum of three numbers in geometric sequence is 14. if the first two terms are each increased by 1 and the third term decreased by 1, the resulting numbers are in an arithmetic sequence. find the...
the third term of a geometric sequence is 6 and the fifth is 81 times the first term. write the first five terms of the progression, assuming the terms are positive
indicate where these are a) geometric, arthmetic or neither b) If geometric, give the common ratio. If arithmetic, give the common...
I feel we have two unknown values here, either the first term or sum to infinity should have been given. I think so! Help
