A man saved 33000 in 10 months. In each month after the first, he
saved + 100 more than he did in the preceding month. How much did
he save in the first month?​

Answer 1

Answer:

amount saved in 1st month = 2850

Step-by-step explanation:

here ,

S(10) = 33000

common difference = 100

A(1) = a

we know,

S(10) = (10/2) [ 2a + (10-1) (100) ]

=> 33000 = (5) [ 2a +900 ]

=> 6600 = 2a + 900

=> 2a = 5700

=> a = 2850
