, 8/7, 9/7....Step-by-step explanation:
, 8/7, 9/7....Step-by-step explanation:Let the first term be A and Common difference be D
, 8/7, 9/7....Step-by-step explanation:Let the first term be A and Common difference be DWe know that Sum of n terms = n/2[2a + (n-1)d], where
, 8/7, 9/7....Step-by-step explanation:Let the first term be A and Common difference be DWe know that Sum of n terms = n/2[2a + (n-1)d], wheren = number of terms, a = first term, d = common difference
, 8/7, 9/7....Step-by-step explanation:Let the first term be A and Common difference be DWe know that Sum of n terms = n/2[2a + (n-1)d], wheren = number of terms, a = first term, d = common differenceGiven that Sum of first 7 term = 10
, 8/7, 9/7....Step-by-step explanation:Let the first term be A and Common difference be DWe know that Sum of n terms = n/2[2a + (n-1)d], wheren = number of terms, a = first term, d = common differenceGiven that Sum of first 7 term = 10∴ 7/2[2A + 6D] = 10
, 8/7, 9/7....Step-by-step explanation:Let the first term be A and Common difference be DWe know that Sum of n terms = n/2[2a + (n-1)d], wheren = number of terms, a = first term, d = common differenceGiven that Sum of first 7 term = 10∴ 7/2[2A + 6D] = 1014A + 42D = 20 ----- ( i )
