2 is a common factor for both of them.
<u>Answer:</u>
- The first four terms are <u>4</u><u>,</u><u>8</u><u>,</u><u>1</u><u>2</u><u>,</u><u>1</u><u>6</u>
<u>Step-by-Step </u><u>Explanation</u><u>:</u>
The given relation between the nth term and it's previous term is given by:

GiveN:
Now finding the other three terms of the AP with the given relation.

Putting a1 = 4,

Now, Third term:

Putting a2 = 8,

Now, Fourth term:

Putting a3 = 12,

Hence, The first four terms of the AP is 4, 8, 12 & 16.
Answer:
A
Step-by-step explanation:
5 and 7 are both common factors of 35 and 40
Looking at the options you can eliminate C and D right away because 7 times 8 = 56 and not 40 like the problem is asking.
This leaves A and B. Looking at the equation the difference between the two are the + and -
Using the original equation (35x-40) as reference we see that it subtracts the two variables. Therefore leaving A as the answer
1, y=(X+1)/3
3, X-2=(-1)/(1/y-3) slove for y.
y= (-1)/(x-2) +3
The answer is 1 USD = 1.0343 AUD
because the ratio is 1 USD:1.0343 AUD
fraction is
1.0343AUD/1USD
use to cancel out units
1.0343AUD/1USD times 80 USD=82.744 AUD
the answe ris the first one
