yˆ=20646*0.86(11)

yˆ=20646*9.46

yˆ=20646*9.46

yˆ=195311.16

Can anyone help with the question ! Thanks <3
Artist 52 [7]

Answer:

26, 42

Step-by-step explanation:

2, 4, 6, 10, 16

This sequence is a_n=a_{n-1}+a_{n-2}  ⇒  the next term is the sum of the previous 2 terms.

Therefore, the next 2 numbers in this sequence would be:

10 + 16 = 26  and 26 + 16 = 42
