Question

Find the 12th term of AP with first term 1/2 and common difference 1/12

Answer 1

Answer:

a₁₂ = 17/12

Step-by-step explanation:

nth term in an AP formula = aₙ = a+(n-1)d

a=first term = 1/2

d=common difference = 1/12

n=no. of terms

a₁₂=1/2 + (12-1)1/12

a₁₂ = 1/2 + 11/12

a₁₂ = 6/12 + 11/12

a₁₂ = 17/12

Answer 2

Answer:

12th term of the A.P = 17/12

Step-by-step explanation:

a=first term

a=1/2

d=common difference

d=1/12

let number of terms=n

then n=12

n term=a+(n-1)×d

a¹²=1/2+(11×1/12)

a¹²=1/2+11/12

a¹²=(11+6)/12

a¹²=17/12
