Question

Complete the pattern 5,10,30,60,180, ?

Answer 1

540 is the answer because the doubled the first number to get the second number and multiplyed that by 3 to get the third number

Answer 2

Let

`a1=5 \\ a2=10\\ a3=30\\ a4=60\\ a5=180`

we know that

`(a2)/(a1) = (10/5)=2 \\ a2= a1*2`

`(a3)/(a2) = (30/10)=3 \\ a3= a2*3`

`(a4)/(a3) = (60/30)=2 \\ a4= a3*2`

`(a5)/(a4) = (180/60)=3 \\ a5= a4*3`

The pattern is times two then times three then times two then times three

so

the sixth term will be

`a6=a5*2`

`a6=180*2=360`

therefore

the answer is

`360`
