Hmm I’ve done this before but I can’t remember sorry but I will try and think
Answer:
3 × 5 ^ n
Step-by-step explanation:
since the series is exponential, the ratio between adjacent terms is 5.
nth term of geometric/exponential series is given by:
nth term = first term × (ratio)^(n-1)
= 15 × 5^ (n-1)
= 15 × 5^n × 5^-1
= 3× 5^n
Answer:
It should be 235.5
Step-by-step explanation:
4a-13=19 add 13 to both sides
4a=32 divide by 4 on both sides
a=8
11 works because 11-5-4 is 2.
-1 also works because it is an absolute value question so it will also equal 2.
