Question

If your good at maths help me

Answer 1

6n+1

Explanation:

first term=13-6=7

nth term=7+(n-1)6=7+6n-6=6n+1

Answer 2

aₙ= 6n +1

Explanation:

Second term a₂= 13

Common difference d= 6

Then first term

• a₁= 13 -6= 7

nth term:

• aₙ= a₁ + (n-1)d
• aₙ= 7 + (n-1)*6= 7+6n -6 = 6n +1
• aₙ= 6n +1
