Answer» a = 2 , d = 4, an =50 an = a + (n-1)d50 = 2 + (n-1)(4)50 - 2 = 4(n-1)48 = 4n - 44n = 48 + 44n = 52n = 52÷ 4n = 13 Answer - 148 is wrong Answer 13 = n is right Sorry for my mistake First one solution method is wrong so please do see as right answer . Let a = 2 , d= 4 Let an be 50 So , we have to find n = ?an = a + ( n - 1 ) d Put the values of a , d , an in formula 50 = 2 + (n - 1) 450 = 2 + 4n -4 50 = -2 +4n 50+2 = 4n 52 / 4 = n 13 = n So the value of n is 13 Given that : AP : 2,6,10.........50Let a = 2 , d = 4 Let an be 50 Now we have given n = 50an =a+(n - 1)d50 = 2+(50 - 1) 450 = 2+ 49 × 4 50 = 196+2 50 = 19850 - 198 = -148So Answer is - 148
