Question

33333

Answer 1

I m not sure about the first question, but for Q6, I think I might have an idea.

From 140 to 133, the difference is 7. From 133 to 126, the difference is 7 also. From here, you can get the idea that the difference between each number is 7.
Let's take 140 to be 'x'. If 'x' is 140, then 133 is 'x-7', and 126 is 'x-14', ans so on and so forth.
You said there were 33 terms. That means, the sum will be:
x + (x - 7) + (x -14) + (x - 21)... + (x - 224)
The last number is (x - 224) because 32 x 7 is 224. Each time, the number will decrease by 7.
Just add everything up. You will get 33x - (7+14+21...+224). Solve it.
33x - 3696
Since x = 140, 33x = 4620, and 33x - 3696 = 4620 - 3696 = 924
That is the answer:)
