What is the recursive formula for this geometric sequence 2, -10, 50, -250

Step-by-step explanation:

Given

Geometric sequence: 2, -10, 50, -250

Required

Recursive formula of the sequence

We start by naming each sequence

Represent each term in relation to the previous term (except T1)

Recall that

So, at this point; we have to make substitutions

Subtract 1 from each term on the right hand side

Replace each term greater than 1 by n

Remove repetition

Hence, the recursive formula is

a

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
