Since our sum is 62, and we have consecutive numbers being added, our range is most likely going to be from 10-20. To further solve this problem easily, try finding 4 consecutive numbers with the ones place adding up to 12, 22, 32, 42, or any number that sums up to the 2 in the ones place. Let's try 14, 15, 16, 17, since 4, 5, 6, and 7 sum up to a number with a 2 in the ones place. 14 + 15 = 29, 16 + 17 = 33. 33 + 29 is 62. We have found the age of the friends, but we're looking for the oldest. Our largest number is 17. Your answer is 17 years old. I hope this helps!
