The problem shown in the image asks you to calculate a sequence where each term is the previous term plus an increasing amount.

The first term is 74. To get the second term, you are instructed to subtract 4 (add $-4$). For each subsequent term, you increase the amount added by 1.

Here’s how you would proceed:

1. First term: $74$
2. Second term: $74 + (-4) = 70$
3. Third term: $70 + (-3) = 67$
4. Fourth term: $67 + (-2) = 65$

Each time, you reduce the negative number being added by 1 (so the value added increases by 1 in absolute terms).

Would you like me to continue the sequence or provide further details?

Here are 5 related questions you might explore:

1. How can you generalize the formula for the $n$-th term in this sequence?
2. How does this sequence relate to arithmetic sequences?
3. Can you derive a formula to find the sum of the first $n$ terms?
4. What happens if the regularly increasing amount grows larger than the first term?
5. How would this sequence change if the starting number was different?

Tip: Sequences like this can often be described using a recurrence relation, which is a way of defining a sequence based on its previous terms.
