Answer:

See explanation below.

Step-by-step explanation:

We have the statement that says that the sum of two two-digit numbers is a three digit number.

To prove that this statement is false, we only need to give a counterexample. This means that we have to find two two-digit numbers that does not sum a three digit number.

Let's take 11 and 12, if we sum them we have: 11 + 12 = 23.

23 is clearly a two digit number.

Therefore, the sum of two two-digit numbers is not a three digit number.

Step-by-step explanation:

Given :-

A sequence 4 , 9 , 14 , ...

And we need to find out the 110th term . the given sequence is in Arithmetic progression . So the common difference is 9 -4 = 5 . Now using the formula to find out the nth term of AP ,

Using formula :-

$:\implies$ T_n = a + ( n -1)d
