​

Answer 1

In this question ;

In this question ; a = 1 ;. d = 4 - 1 = 3 ;. tn = 176

In this question ; a = 1 ;. d = 4 - 1 = 3 ;. tn = 176 By formula

In this question ; a = 1 ;. d = 4 - 1 = 3 ;. tn = 176 By formula Tn = a + ( n - 1 ) d

In this question ; a = 1 ;. d = 4 - 1 = 3 ;. tn = 176 By formula Tn = a + ( n - 1 ) d 176 = 1 + ( n - 1 ) 3

In this question ; a = 1 ;. d = 4 - 1 = 3 ;. tn = 176 By formula Tn = a + ( n - 1 ) d 176 = 1 + ( n - 1 ) 3176 = 1 + 3n - 3

176 + 2 = 3n

176 + 2 = 3n 178 ÷ 3 = n

176 + 2 = 3n 178 ÷ 3 = n ~ 59 = n

176 + 2 = 3n 178 ÷ 3 = n ~ 59 = n Hope this helps you
