Sagot :

Answer:

i) 8

ii) yes 400 is a value in the sequence as the nth term would be 200 for that, 400 is also divisible by 2, and as 2 is the coefficient of n, 400 can be a value in the sequence.

Step-by-step explanation:

for n as term number:

n = 4

2n = 8

i) 8 is the fourth term

for n as unknown:

2n = 400

400/2 = n

200 = n

ii) yes 400 is a value in the sequence as the nth term would be 200 for that, 400 is also divisible by 2, and as 2 is the coefficient of n, 400 can be a value in the sequence.
