ARITHMETIC
SEQUENCE
12) Consider the A.S 4,8,12,
a) calcubete common difference ?
b) Find the 25th teams of the sequences​

Answer 1

AS : 4, 8, 12, ......

therefore, common difference = 8 - 4 = 4

now,

n = 25 (given)

a = 4

d = 4

therefore, an= a+ (n-1) d

an= 4 + (25-1) 4

an= 4 + 24×4

an= 4 + 96

an= 100

Hence, common difference is 4 and 25th term is 100
