Dear t.elia could you please politely tell me the nth term and sequence
can you please answer the following questions-a)3n=1.5 b) 2n+0.5 c)4n+1.5 d) 3n+2.5 e) 4n+0.5 f) 6n+2.5 g) 5n+3.5 h) 6n+3.5 h) n+7.5
Thank you
Hi Humy1308,
3n = 1.5
Divide each side by 3 to get "n" on its own
The two 3's on the left hand side will cancel each other out leaving you equation as;
n = 1.5 / 3
= 0.5
n = 0.5 (ans)
Question b
2n + 0.5
Rewrite as follows;
2n + 0.5 = 0
Bring the 0.5 over the = sign to the other side, it now becomes negative 0.5 ( change side , change sign) ok so far
So we'll now do your equation;
2n + 0.5 = 0
2n + 0 - 0.5
2n = - 0.5
Divide each side by 2 to get "n" on its own
the two's on the left hand side of the equation will cancel each other, leaving "n" on its own.
so now we have;
n = - 0.5 / 2
n = - 0.25 (ans)
Questions (C to H ) work in exactly the same way as question B
So try these on your own and let me know how you get on please; always divide by the correct number to get "n" on its own.
Question I
n + 7.5
Rewrite as follows;
n + 7.5 = 0
Bring the 7.5 over the = sign to the other side, it now becomes negative 7.5 ( change side , change sign) ok so far
So we'll now do your equation;
n + 7.5 = 0
n = 0 - 7.5
n = - 7.5 (ans)
Use your calculator when dividing to find the answers to these questions.
Good Luck

How do you politely tell someone they have overstayed their welcome?For example, you had a party that ended at 2pm and it is now 5pm. After throwing a party, you just want some down time with no deep thought conversation involved.
