13, start with 24, right? 24 plus 6 is 30. 30 minus 12 is 18. 18 minus 5 is 13.
Answer:
For 100, your answer will be 102; For 898, your answer will be x; 100*x = 102*898 ... 102/x = 100/898 or x/102 = 898/100; x = 898*102/100 = 91596/100 = 915.96.

Answer:
-256 +64 - 16 + 4 - 1
Step-by-step explanation:
A series is the summation of all the terms in a sequence.
So it is only the last three options that qualify to be a series.
The series 2 +5 + 8 + 11 + 14 + 17 has no common ratio. It is not geometric.
The series 1+1+2+3+5+ 8 +13 +21 also has no common ratio. It is not geometric.
The series -256 +64 - 16 + 4 - 1 has a common ratio of

There the only series that is geometric is.
-256 +64 - 16 + 4 - 1
