Question

The sequence is recursive. Find the value of the next term in the sequence.
15, 26, 48, 92, . .

Answer 1

I think it is
\[\large a_n=a_{n-1}\cdot2-4 \]
for n>1.

Answer 2

26-15=11=11*1
48-26=22=11*2
92-48=44=11*4
92+11*8=?

Answer 3

lol @surjithayer I didn't notice that

Answer 4

The whole thing with recursive relationships is they depend on the previous term. I feel like what @helder_edwin is saying helps to understand them a little better.

Basically what he's saying is the the next term is simply the previous term *2 -4

Answer 5

15*2 -4 = 26
26 *2 - 4 = 48
48*2 - 4 = 92
92*2 - 4 =

Answer 6

\[a _{1}=15\]
\[a _{n+1}=15+11\left( 2 \right)^{n-1}\]
\[n \ge 1\]or n is a natural number.
