Aplayground is being designed where children can interact with their friends in certain combinations. if there is 1 child, there can be 0 interactions. if there are 2 children, there can be 3 interactions. if there are 3 children, there can be 12 interactions. if there are 4 children, there can be 39 interactions. which recursive equation represents the pattern? an = an – 1 + 3(n – 1) an = an – 1 + 3(n – 1) an = an – 1 + (3n – 1) an = an – 1 + (n – 1)3

Step-by-step explanation:

It is given that

If there is 1 child, there can be 0 interactions.

If there are 2 children, there can be 3 interactions.

If there are 3 children, there can be 12 interactions.

If there are 4 children, there can be 39 interactions.

It means we have,

We need to find the recursive equation that represents the pattern.

Similarly,

Therefore, the required recursive formula is .

d

step-by-step explanation:

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
