Since this is a sequence, so we have to observe its first
two terms:
First digit + Second digit = Resultant
2+3=8 means 2*3+2=8
3+7=27 means 3*7+6=27 3*2=6
(The additional term 6 is the product of first digit (3) of
the operational term, i.e. 3+7 and first digit (2) of the
preceding term i.e. 2+3)
4+5=32 means 4*5+12=32 4*3=12
(The additional term 12 is the product of first digit (4) of
the operational term, i.e. 4+5 and first digit (3) of the
preceding term i.e. 3+7)
5+8=60 means 5*8+20=60
6+7=72 means 6*7+30=72 (6*5=30)
(The additional term 30 is the product of first digit (6) of
the operational term, i.e. 6+7 and first digit (5) of the
preceding term i.e. 5+8)
Therefore:
7+8=98 means 7*8+42=98 (7*6=42)
(The additional term 42 is the product of first digit (7) of
the operational term, i.e. 7+8 and first digit (6) of the
preceding term i.e. 6+7)
Hope it is clear now.
