Question

А1=-24d=3a29-?S16-?a1=3 a2=6​

Answer 1

Объяснение:

$a_1=-24\ \ \ \ d=3\ \ \ \ a_{29}=?\\a_{29}=a_1+28d=-24+28*3=-24+84=60.$

$a_1=3\ \ \ \ a_2=6\ \ \ \ S_{16}=?\\d=a_2-a_1=6-3=3.\\S_{16}=\frac{2*3+15*3}{2}*16=(6+45)*8=51*8=408.$

Answer 2

It appears that you've provided a series of variables and equations, but it's not clear what you're asking or what you'd like to know.

You've listed variables A1, a, S, a1, and a2, along with some equations, but there are missing elements and unclear symbols. To help you better, please provide more context and clarify your question. Additionally, make sure to use standard mathematical notation so that it's easier to understand what you're trying to convey.
