The nth term of a sequence is 8(n+3)
what is the 30th term?
what is the nth term for this sequence?

30th term: 364

nth term: 8(n + 3)

Step-by-step explanation:

Well the 30th term is 8(30 + 3) because you gotta plug it in.

You get 8 * 33 = 264

nth term is what they gave you. 8(n + 3)

30th term: 364

nth term: 8(n + 3)

Step-by-step explanation:

Well the 30th term is 8(30 + 3) because you gotta plug it in.

You get 8 * 33 = 264

nth term is what they gave you. 8(n + 3)

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
