okkkkkkkkkkkkkkkkkk

Answer 2

Answer:

- 77

Step-by-step explanation:

NOTE :

• Tn = a + ( n - 1 ) d
• a = 1st term = 10
• n = no. of term = 30
• d = common difference = 2nd trem - 1st term = 7 - 10 = - 3

Tn = a + ( n - 1 ) d

=> T30 = 10 + ( 30 - 1 ) (-3)

=> T30 = 10 + 29 (-3)

=> T30 = 10 + (-87)

=> T30 = 10 - 87

=> T30 = - 77
