Answer:

Last term of an Arithmetic Progression is 116/3

Explanation:

Given

sum of 12 terms of an AP=256

first term 'a'=4

we have to find last term

Formula for sum of 12 terms of an AP is given by

s_{n}  =  \frac{n}{2} (a + l) \\ </p><p>s_{12} =  \frac{12}{2} (4 + l)

256 = 6(4 + l)

4 + l =  \frac{256}{6}

l =  \frac{256 - 24}{6}

  =  \frac{232}{6}  =  \frac{116}{3}

Hence last term of an Arithmetic Progression is 116/3
