Question

Aman swims 1.5 mi on Monday, 1.6 mi on Tuesday, 1.8 mi on Wednesday, 2.1 mi on Thursday, and 2.5 mi on Friday. If the pattern continues, how many miles will he swim on Saturday?

Answer 1

Aman will swim `3.0` miles on Saturday.

Explanation:

Look at the numbers in a sequence.

`1.5, 1.6, 1.8, 2.1, 2.5`

Determine the change from each term to the next.

`+0.1, +0.2, +0.3, +0.4`

As you can see, the next term will be equal to `2.5 + 0.5`, or `3.0`.
