Answer:
d = 3
Step-by-step explanation:
Expand the right side and compare the coefficients of like terms
x² + 6x + c = x² + 2dx + d²
For the 2 sides to be equal then coefficients of like terms must be equal
compare coefficients of x- terms, then
2d = 6 ⇒ d = 3
Answer:
Step-by-step explanation:
Given that,
We need to find the 15th term of the sequence. Put n = 15 in the above sequence so that,
So, the 15th term of the sequence is 8.
