How to work out questions like these, in detail

Let the missing number be x,

For the first question, the equation is as follows,
x - 13 = 29

Solve for x,
x - 13 + 13 = 29 + 13
x = 42

The equation would then be 42 - 13 = 29

For the second question, the equation is as follows,
x - 12 = 203

Solve for x,
x - 12 + 12 = 203 + 12
x = 215

The equation would then be 215 - 12 = 203

42-13=29 and

215-12=103

Hope this helped!!!

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
