Given:
1,5,25,61.....
To find:
The following number.
Solution:
We can see a pattern in the given sequence.




Using this pattern the next term is the sum of squares of 7 and 8.

Therefore, the next number is 113.
The unit rate of 240 miles in 6 hours would be 40 miles per hour.
Answer:
5 years ago
Let Kelly's age be x
Jake's age is 4x
5 years later
Kelly's age is x + 5
Jake's age is 4x+5
The sum of both their ages is 60. The equation will be
x + 5 + 4x + 5 = 60
5x + 10 = 60
5x = 60 - 10
x = 50/5 = 10
So Kelly is (10 + 5) 15 years old.
Jake is (4*10 + 5) = 45 years old
Your car will take you 23 miles on the first gallon, 23 miles on the second gallon, 23 miles on the third gallon, and 23 miles on the fourth gallon. The total distance is 92 miles, and if you have not added more gas by that time, it will all stop right there.
If it was added to water then the answer will be the first one (it would dissolve)
