In this question, it is given that the eighth term is 78 and the explicit formula is

And the recursive formula is

And we have to find the 20th term . And for that, we put 20 for x in the explicit formula. That is

Therefore on using the explicit formula, we will get 198 as the 20th term .

The angles of the triangle are given as to have measures of 45°-45°-90°. This entails that the triangle is an isosceles triangle where the 2 legs of the triangle are of equal length. We calculate as follows:
c² = a² + b²
c² = 2a²
4² = 2a²
a = 2√2
