Question

How can i answer this?

Answer 1

Listed below.

Explanation:

• To solve number 1, we can simply finish the pattern:

2a, 3d, 4c, 5d, 6e, 7f, 8g...

We can do this by adding 1 number each time, 2 + 1 = 3...etc., then we go down one letter in the alphabet. a, b, c, d...etc.

• To solve number 2, we just add one number each time to x.

(Remember, 1x = x)

x, 2x, 3x, 4x, 5x, 6x... etc.

• To solve number 4, we can just name the alphabet, skipping over one each time.

A, B, C, D, E, F, G, H... etc.

• To solve 4, we can add 2b each time.

a + b + 2b = a + 3b

a + 3b + 2b = a + 5b

a + 5b + 2b = a + 7b... etc.

• Finally, to solve for number 5 we can just add +
  `?^(2)` each time

`r^(1) + r^(2)= r^(3)`

`r^(3)+ r^(2) = r^(5)` ... etc.
