A frog is at the bottom of a well 10 feet deep.
He can jump 3 feet, but every time he jumps 3 feet,
he falls back 2 feet.
How many jumps will he have to make to get out of the well?

• 8 jumps are needed
  (3-2)+(3-2)+(3-2)+(3-2)+(3-2)+(3-2)+(3-2)+3=10 feet

• 8th term jump

• 8 jumps to make get out of the well.
  
  For every jump, he jumps only 1 feet. (Because , every 3feet, he fall back 2feet)
  
  So, for 7jumps, he reach 7feets.
  
  In 8th jump, he reach 7+3ft = 10feet and get out of the well.
  
  So, 8 jumps needed.

• 8 jumps is the answer
  Reason: The frog climbs= 3 feet per jump
  It falls = 2 feet per jump
  total rise = 1 feet per jump
  doing this continously up to 6 jumps it climbs= 18 feet
  but falls= 12 feet
  total rise in 6 jumps= 18-12= 6 feet now he is at 6 feet he has to climb 4 more feet
  in the 7th jump again he climbs 1 more foot(3 rise-2 fall) and reaches to 7 feet mark but still needs 3 feet to jump out of the well
  therefore in final 8th jump he will be out of the well, 7+3= 10 feet.

• In 7 jumps, it will cover 7 feet.
  In 8th jump, it will move out of well.
