A recursive sequence is one where the next term is a specific combination of the previous terms. In this question, the recursive sequence is created where the next term is the sum of the previous two terms. This is called the Fibonacci sequences. Look at this sequence of numbers: 1, 1, 2 ,3, 5, 8, 13, 21……. Level 1-2: (a) Write down the next two numbers in this sequence

34, 55.

Step-by-step explanation:

The next 2 numbers are 13+21 = 34 and 21+34 = 55.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
