An= A1 + d(n-1)
An= 170 + (-85)(n-1)
An=170-85(n-1)
An= 170-85n+85
Answer: An=255-85n
Answer: 75%
Step-by-step explanation:
Answer:
210
Step-by-step explanation:
so the four Smallest Primes
:
2, 3, 5, 7
When the number is Divided by 2, 3, 5 & 7 Leaves remainder 1
so N = 2a + 1
N = 3b + 1
N = 5c + 1
N = 7d + 1
-> N - 1 = 2a = 3b = 5c = 7d
N - 1 = 2 * 3 * 5 * 7
-> N - 1 = 210
-> N = 211
Next N - 1 = 2(210)
-> N - 1 = 420
-> N =421
Difference = 421 - 211 = 210
Answer:
486
Step-by-step explanation:
for the 2nd term, add 5 to -9
for the 3rd, add 5 × 2 to -9
for the 4th, add 5 × 3 to -9
:
for the 100th, add 5 × (100 - 1) to -9
=> 5 × 99 + (-9)
=> 486
You just combine like terms so it'll be 5x^43
