Let's simplify step-by-step.

3t−3+6t2+4t+13−8t2+11t−1

=3t+−3+6t2+4t+13+−8t2+11t+−1

Combine Like Terms:

=3t+−3+6t2+4t+13+−8t2+11t+−1

=(6t2+−8t2)+(3t+4t+11t)+(−3+13+−1)

=−2t2+18t+9

the sum of the first 6 terms of a geometric series is 15624 and the common ratio is 5. what is the first term of the series?
9966 [12]

Answer:

first term a=4

Step-by-step explanation:

Sum of the first 6 terms S6 = 15624

common ratio r= 5

n= 6

first term a=?

Formula: S6= a(r^n-1)/r-1

15624 = a( 5^6-1)/5-1

15624 = a(15625-1)/4

15624= a( 15624)÷4

15624= 15624a÷4

Cross multiply

15624×4 = 15624a

62496 = 15624a

divide both sides by 15624

62496÷15624 = 15624a÷15624

4 = a

a= 4
