Consider that an = 4n-1 represents a sequence. what is the tenth term? a) 361 b) 512 c) 1,024 d) 4,096 e) 262,144

Hello from MrBillDoesMath!

Choice E.

Discussion:

Assuming that n >=1, a(n) = 4n -1, then

a(10) = 4(10) - 1 = 39    

but that doesn't match any of the answers hmm...

BUT

If you meant that a(n) = 4^(n-1),  then

a(10) = 4^(10-1) = 4^9 =  262144    

which is Choice E.

Thank you,

MrB

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
