Answer: 105750
Step-by-step explanation:
From the sequence 9, 33, 57, 81, 105, the following can be derived:
a = First term = 9.
d = Common difference = 33 - 9 = 24
n = Number of terms = 94
The sum of the nth term will be:
= n/2[2a + (n – 1)d]
= 94/2 [(2 × 9) + (94 - 1) × 24]
= 47 [18 + (93 × 24)]
= 47[18 + 2232]
= 47 × 2250
= 105750
Therefore, the sum of the 94 terms of the sequence is 105750.

Answer:
f(4)=6
Step-by-step explanation:
replace a with 4
f(4)=2(4+2)-6
the multiply thingy(i forgot what it was called ok) (2*4 and 2*2)
f(4)=8+4-6
do the easy math(i will write it out anyways though)
f(4)= 12-6
f(4)=6
i havnt done this for a while but this is what i remeber
dont report me if i was wrong pls
