To determine

Pattern and next two term for the given sequence “1.1, 2.2, 3.3, 4.4, …..”.

Answer to Problem 15PPE

The pattern is “Each next term is 1.1 more than the previous term”.

And next two terms are 5.5 and 6.6.

Explanation of Solution

Given:

The given sequence is,

1.1, 2.2, 3.3, 4.4,

Here,

  $\begin{array}{l}2.2-1.1=1.1\\ 3.3-2.2=1.1\\ 4.4-3.3=1.1\end{array}$

So, the pattern followed in given sequence is

“Each next term is 1.1 more than the previous term”

So, the next two term will be

  $\begin{array}{l}4.4+1.1=5.5\\ 5.5+1.1=6.6\end{array}$
