i’m kinda confused on what arithmetic and geometric is? i don’t understand this question or how to do it:(

Geometric

Step-by-step explanation:

Arithmetic sequences are where there's a common difference. For example, in the sequence 1,2,3,4,5,6, there's a common difference of 1, showing that each term is added to 1 to get the next term. This goes for subtraction too.

Geometric sequences are where there's a common ratio. For example, in the table you gave, each term is being multiplied by 2. 6*2=12, 12*2=24, 24*2=48, and so on. The common ratio is 2 because 12/6=2, 24/12=2, and 48/24=2.

Hope this cleared things up!

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
