Answer:
1385
Step-by-step explanation:
1) the difference is d=25-8=42-25=17;
the sequence given in the condition is arithmetic one (linear relationship).
2) in order to calculate the value of the 82d term:
a(n)=a(1)+d*(n-1), where n - number of required term (it is 82), then
a(82)=8+17*(82-1)=8+1377=1385.
Answer:
Step-by-step explanation:
c.d=-15,-17,-19,...
it is neither arithmetic nor geometric.
But common difference is arithmetic.
Let, the number = x
So, x * 1/10 = 0.04
x = 0.04 * 10
x = 0.4
So, your final answer is 0.4
Hope this helps!
Answer:
correct / incorrect / incorrect
Step-by-step explanation:
5a - 8 + 2a² + 2a - 1 ← collect like terms
= 2a² + 7a - 9 ← correct
-------------------------------------
b² + 6b - 4 - (3b + b²) ← distribute parenthesis by - 1
= b² + 6b - 4 - 3b - b² ← collect like terms
= 3b - 4 ≠ 2b² + 3b - 4
---------------------------------------
9c - 4c² - (2c² + c) ← distribute parenthesis by - 1
= 9c - 4c² - 2c² - c ← collect like terms
= - 6c² + 8c ≠ - 6c² + 10c
If you are looking for the value of N, multiply both sides by 4. The value of N is 4900.
