Step-by-step explanation:
by solving it we get,
=》a - 32 = 47
=》a = 47 + 32
=》a = 79
hence, a = 79
Answer:
47, 40, 33, 26 are the first four terms of the sequence.
Step-by-step explanation:
Expression representing the sequence is,

where n = number of term in the sequence
For n = 1,

= 47
For n = 2,

= 47 - 7
= 40
For n = 3,
= 47 - 7(3 -1)
= 47 - 14
= 33
For n = 4,

= 47 - 21
= 26
Therefore, first four terms of the sequence are 47, 40, 33 and 26.
