Answer by JKismyhusbandbae: add 5 to 23
Explanation: The numbers are increasing by 5 each term. To double check 13 - 8 equals 5. To make sure it's right add 13 + 5 equals 18 and so you can add 23 plus 5 equals 28. Which means that five is our pattern.
Answer:
For this, first you must multiply the exponent, which in this case is 1.06^15,
and this gives you 2.39655819.
You then multiply 2.39655819 by 200000.
y = 479311.638
