Question

Trent lifts weights 7 days a week. He spends 18 minutes lifting weights on Monday, 29 minutes on Tuesday, 40 minutes on Wednesday, and 51 minutes on Thursday. If this pattern continues, how many minutes will Trent lift weights on Saturday? ​

Answer 1

73 minutes

Explanation:

Find a pattern in the sequence.

The sequence is 18, 29, 40, 51.

29 - 18 = 11

40 - 29 = 11

51 - 40 = 11

The pattern is add 11 each day.

If 51 is Thursday, 51 + 11 is Friday.

51 + 11 + 11 is Saturday.

51 + 11 + 11 = 73

Therefore Trent will lift weights for 73 minutes.
