Find the next two terms in the number sequence 11,23,48,99

To find the next two terms in the sequence \(11, 23, 48, 99\), let's first analyze the pattern by finding the differences between consecutive terms.

1. Difference between \(23\) and \(11\): \(23 - 11 = 12\)
2. Difference between \(48\) and \(23\): \(48 - 23 = 25\)
3. Difference between \(99\) and \(48\): \(99 - 48 = 51\)

The differences between the terms are \(12, 25, 51\).

Now, let's look at the differences between these differences:

1. Difference between \(25\) and \(12\): \(25 - 12 = 13\)
2. Difference between \(51\) and \(25\): \(51 - 25 = 26\)

The second differences are \(13, 26\), which are doubling each time.

If this pattern continues, the next difference should be:

\[ 26 \times 2 = 52 \]

So, the next difference after \(51\) should be:

\[ 51 + 52 = 103 \]

Adding this to the last term:

\[ 99 + 103 = 202 \]

Now, let's find the next difference following the same pattern:

\[ 52 \times 2 = 104 \]

Adding this to the new term:

\[ 202 + 104 = 306 \]

Thus, the next two terms in the sequence are **202** and **306**.
