I need help so it. Says to subtract:3.8 - 2.923 and to explain in your own words how you would solve it and to put it in detail

0.877  

Step-by-step explanation:

3.800  0 and 3 make the 0 a 10 10 -3=7  0 and 2 0 10 and make the 10 a 9 9-2=7   8 and 9   8 is 17 17-9=8   3 and 2 3 will be 2 and 0

 I'm pretty sure you won't understand because i'm bad at explaining but i hope this helps

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
