Answer 1

Answer:

164

Step-by-step explanation:

d=12

a=3

tn=501

n=?

tn=a+(n-1)d

501=12+(n-1)3

501=12+3n-3

501=3n+9

501-9=3n

492=3n

492/3=n

164=n

Answer 2

Step-by-step explanation:

a = 12 , d = a2 -a1 = 15-12 = 3,an= 501

an = a+(n-1) d

501 = 12 + (n-1) × 3

501 -12 = (n-1) 3

489 = (n-1) ×3

489/3 = (n-1)

163 = (n-1)

163+1 = n

n = 164

164 term of ap is 501
