Answer 1
Answer:

Answer:

- 508

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_(n) = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 28 and d = - 34 - (- 28) = - 34 + 28 = - 6, thus

a_(81) = - 28 + (- 6 × 80) = - 28 - 480 = - 508

What is the nth term to: 0,6,14,24,36,50

Answers

0, 6, 14, 24, 36, 50, 66, 84,104 

you add 9 times for each one


This is the sequence; +6,+8,+10,+12,+14

Now to find the next terms you must add 2 only to the sequence;

+6, +8, +10, +12, +14, +16,

Then add the +16 to the term and you get: (50 + 16) =66

so 66 is the 7th term and to get the 9nth you must do same steps;

+6,+8,+10,+12,+14,+16,+18,+20:

66+18 = 84 (8th term)

84 +20= 104 (9nth term)

So your final terms are;

0, 6, 14, 24, 36, 50, 66, 84,104
