Question

Write a recursive formula for the sequence 15, 26, 48, 92, 180

ok i think it is an = 2an – 4 where a1 = 15; 356

Answer 2

not sure

Answer 3

is the fourth term 180??? or 190????

Answer 4

the fourth term is 92

Answer 5

your recursive formula is right, but you wrote it a bit off

Answer 6

180 @anusha.p

Answer 7

\[a_1=15\]\[a_n=2a_{n-1}-4\]make sure you put the \(a_{n-1}\) part in there or it's not recursive

Answer 8

\(\Large \color{midnightblue}{\rightarrow a_n = 2a_{n - 1} - 4 }\)

Get it?

Answer 9

k ill put it in my notes thank u

Answer 10

We're using a function that doubles the previous value of the sequence and subtracts by 4.

Answer 11

If n is the current value, then n - 1 is the previous value. Put the thing I'm talking about in the notes please.

Answer 12
