Find the 97th of the arithmetic sequence 25, 29, 33, ...
1 answer:
Answer:
434
Step-by-step explanation:
hello :
note : the n th term of an arithmetic sequence is :
An =A1+(n-1)d ....a common difference is : d and A1 the first term
in this exercice : d = 33-29 =29-25= 4 A1 = 25
when : n =97 you have the 97rd term A97
so : A97 =25 +(97-1)(4)
A97 = 434

Answer:
3/4 - 6/8
1/3 - 2/6
1/2 - 5/10
3/5 - 6/10
1/4 - 2/8
The slope f'(x) = [f(4) - f(2)]/(4-2)≥3,
so [f(4) - 13]/2 ≥3
f(4) -13 ≥ 6
f(4)≥19, so it can be as small as 19.
