Answer:
First term a = 41
Step-by-step explanation:
Arithmetic Progression:
Common differences d = -2
= 10*(2a - 38)
= 10*2a - 10*38
=20a - 380
= 11 (2a -42)
=11*2a - 11*42
= 22a - 462
22a - 462 = 20a - 380
22a = 20a - 380 + 462
22a = 20a + 82
22a - 20a = 82
2a = 82
a = 82/2
a = 41
First term a = 41
