Find the tenth term in the sequence
that is defined as follows:
an = 2(-1)"

2

Step-by-step explanation:

For a sequence an = ar ∧ n-1

for the sequence

an = 2(-1)∧ n

Note n = 2

an = 2(-1)∧ 10

a10 = 2 x 1

a10 = 2

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153

you have 6 equal triangles, find the area of one of them (b*h/2) and multiply by 6

(8*4: 2)*6 =

32 cm² is your answer
