ARITHMETIC PROGRESSION 1

The 1st term of an A.P. is 16 and the common difference is 24. Find the 10th term.

Solution                                               

A₁= 26, d = 24

A_n = A₁ + (n-1)d

A₁₀ = A₁ + (10-1)d

A₁₀ = A₁ + 9d

A₁₀ = 26 + (9x24)

A₁₀ = 26 + 216

A₁₀ = 242

Hence the 10th term is 242.
