Even number are of the form 2n. The sum of this sequence is the average of the first and last terms times the number of terms.
So the first term is 2 and the 25th term is 50 so the sum is:
(2+50)(25/2)
52*12.5=650
The conjecture they wish you to make is that for n terms, the sum will be:
s=n(n+1)
And for 25 terms that would give you:
s=25*26=650
Answer:
Set up camras get ur proof
Step-by-step explanation:
If he made 25 percent profit, the selling price (1200 naira) is 125 percent.
If 125% is equal to 1200 naira
100 percent (the original) will be 100 × 1200 divided by 125
Which is 120000 ÷ 125
Therefore, the cost price is 960 naira
Answer:
No they don't form a proportion
Step-by-step explanation:
Their denominatiors do not share a common multiple, therefore they can not form a proportion.
Okay too answer this you have to take the two smallest numbers and add them, in this case the answer would be 5 + 4 = 9. The answer has to be greater than the last number, In this case, 7. So the answer is yes.
