How can you tell if an equation is an "and" or an "or"

Look at this pattern ; 1,4,9, number 10000 belongs in this pattern . what’s the place of this number?

One astronomical unit (1 au) is about 1.496 alt tag missing. kilometers. if you wrote this number of kilometers in regular decimal notation (for example, 528 and 3,459 are written in regular decimal notation), how many zeros would your number have?

Can someone answer and tell me how to do this (will mark brainliest)
