Question

What is the 15th term of the following sequence? 0.25, 0.5, 1, 2, 4…

Answer 1

4,096

Solution:

• In this case, we have a geometric sequence.
• In a geometric sequence, we use multiplication/division in order to get to the next term.
• In this case, we multiply each term by 2.
• So these are the terms:
• 0.25, 0.5, 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1,024, 2,048, 4,096
