Question

Sven includes bike riding in his daily exercise plan. On day 1, he rides around the block 2 times. On the following 4 days, he rides double the number of times he rode around the block on the previous day. How many times does he ride around the block on day 4?

Answer 1

For this case we have an equation of the potential type.
 y = A * (b) ^ x
 Where,
 A: initial amount
 b: rate of increase
 x: number of days
 Substituting values we have:
 y = 2 * (2) ^ x
 For day 4 we have:
 y = 2 * (2) ^ 4
 y = 32 times
 Answer:
 he does ride around the block on day 4 about:
 y = 32 times
